Bilateral ties between Malaysia and the United States were established upon Malayan independence in 1957. The US was, and still is, one of the largest trading partners for Malaysia and is traditionally considered to be Malaysia's oldest and closest ally in military, economic and education sectors. Malaya was the predecessor state to Malaysia, a larger federation formed through the merger of Malaya, North Borneo, Sarawak and Singapore in 1963. Immediately before the merger, the latter three territories were previously part of the British Empire. But the US has had a consular and commercial presence in Malaya since the 1800s. US merchants, especially Joseph William Torrey together with Thomas Bradley Harris, also had commercial interests in the north western coast of Borneo in the 19th century, where they established the American Trading Company of Borneo.

Malaysia has its embassy in Washington, D.C., and consulate-general offices in Los Angeles and New York City. The United States maintains its embassy in Kuala Lumpur. Beginning in April 2014, the US considered Malaysia as a Comprehensive Partner which increased the importance of diplomatic ties as part of President Barack Obama's Pivot to Asia policy. The partnership increased bilateral consultations and co-operation on politics, diplomacy, trade, investment, education, people-to-people ties, security, the environment, science, technology and energy, which continued to be enhanced by President Donald Trump in 2017.

In 2016, the US is Malaysia's third largest export market in terms of value, while Malaysia is the US's 25th largest export destination and among the largest trading partners for the latter.

History

The United States has a long commercial interest in Malaysia, dating back to the 1800s when the territories now part of the Southeast Asian country were part of the British Empire. While Malaysia through Malaya only established a diplomatic presence in the US beginning in 1957, the US had consular posts in Malaya and commercial interests in northern Borneo since the 1800s. In 1850, the US recognised the status of the Kingdom of Sarawak which was established by an Englishman named James Brooke as an independent state. US merchants Torrey and Harris through the American Trading Company of Borneo had a tract of land in the north west of Borneo, which was however sold to Baron von Overbeck in 1876. The US further appointed a consul in George Town in 1918 and established additional consular posts in Kuala Lumpur in 1948 and Kuching in 1968. The modern ties between Malaysia and the US are generally warm, with the US having supported Malaysia during the Indonesia–Malaysia confrontation, an armed conflict arising from Indonesian opposition to the formation of Malaysia, marking the beginning of US direct involvement in the political affairs of Malaysia. Earlier, during World War II, the US played a role in the liberation of Southeast Asia from Japanese occupation, especially in the liberation of Borneo as the island is located close to the Commonwealth of the Philippines, which is a protectorate of the latter. During the Malayan Emergency, the Malayan government and the British colonialists received aid from the United States to suppress the communist independence rebellion.

Political relations, however became strained, under the Bush administration during the Iraq War. Mahathir Mohamad who ruled from 1981 until 2003 was critical of the foreign policy of the United States at the time, especially the foreign policy of the George W. Bush administration's invasion of Iraq during the Iraq War. Nevertheless, these periods of tensions between the two nations did not prevent the US from being one of the largest trading partners for Malaysia during Mahathir's tenure. The US was, and still is one of the largest trading partners for Malaysia and is traditionally considered to be Malaysia's closest ally. In 2002, Malaysia-US Friendship Council was established to strengthen the friendship between the Malaysian government and the US government. Mohd Noor Amin, Chairman of the International Multilateral Partnership Against Cyber Threats (IMPACT), was appointed as the Secretary-General for this council. The council is headquartered in Washington, D.C. and sponsored by leading Malaysian companies to offer advice on matters relating to bilateral relationship between the two countries.

Under the helm of Prime Minister Najib Razak's administration, the two-way diplomatic ties between the two sovereign nations have since warmed and became normalised once more. Subsequently, US President Barack Obama's made his first official visit to Malaysia in April 2014, the first visit by a sitting US president since 1966. Prime Minister Najib and President Obama issued a joint statement that, among other things, elevated the Malaysia-US relationship to a comprehensive partnership. Malaysia is currently pursuing the Trans-Pacific Partnership (TPP) treaty with the support of the US until January 2017. Both countries continue to enjoy warm relations with the two leaders became close personal friends. On Christmas Eve in 2014, both Najib and Obama are seen playing golf together in Hawaii. Following the victory of Donald Trump in the 2016 US presidential election, the relations continue to be strengthened with Najib was among the international leaders that congratulated Trump and looked forward to continuing a partnership with the US under his presidency. In June 2018, the United States Embassy in Kuala Lumpur hosting a series of programs in Sabah (the former North Borneo) to celebrate the 150+ years of partnership with the people of the territory.

On 13 June 2020, former Prime Minister Mahathir Mohamad endorsed former Vice-President Joe Biden in the 2020 US Presidential Election.

In July 2025, President Trump nominated Nick Adams as the new US ambassador to Malaysia. This appointment was met with much opposition and protest in Malaysia. In late October 2025, Trump undertook his first state visit to Malaysia where he attended the 47th ASEAN summit, met with Prime Minister Anwar Ibrahim and signed multiple trade agreements.

Economic relations

The earliest significant economic relations between the territories now part of Malaysia, in particular Malaya, was the US involvement in the production and trade of tin and rubber. Malaya at one time was the largest single producer of both commodities and the US was the largest importer of Malayan tin. By 1917, rubber became Malaya's most important exports and the US absorbed 77% of Malaya's total rubber production. The great demand for rubber was due to the rising production of automobile in Malaysia.

In modern days, the US is one of the largest foreign investors in Malaysia. The American Malaysian Chamber of Commerce serves as a business association for collaboration between both countries. While figures capturing the full range of foreign investment (including oil and gas) are not available, American companies are particularly active in the energy, electronics, and manufacturing sectors and employ nearly 200,000 Malaysian workers. The cumulative value of US private investment in the manufacturing sector in Malaysia is roughly $15 billion. In the 1970s, American companies, including Agilent AMD, Fairchild Semiconductor, Freescale Semiconductor, Intel, Texas Instruments and Western Digital pioneered the Malaysian electrical and electronics (E&E) sector, which exports billions of dollars of equipment to global supply chains every year. Major US oil and gas companies, including ExxonMobil, ConocoPhillips, Hess and Murphy Oil, have invested billions of dollars to develop Malaysia's energy resources. Many US-based fast-food/coffeehouse chains such as A&W Restaurants, Burger King, Domino's Pizza, Dunkin' Donuts, KFC, McDonald's, Pizza Hut, Starbucks, Subway, Texas Chicken and Wendy's have already dominated the Malaysian fast food/coffeehouse markets. Recent US investors include Hershey, Kellogg's, Bose and Golden Gate Capital. The US is Malaysia's fourth largest trading partner and Malaysia is the 22nd largest trading partner of the US. Annual two-way trade in goods and services in 2013 amounted to approximately $44 billion.

Malaysia and the US launched negotiations for a bilateral free trade agreement in June 2005 but did not conclude an agreement after eight rounds of talks. Malaysian investment in the US is small but growing, particularly in leisure, gaming and biotechnology. Significant Malaysian companies operating in the US include Genting's Resort World Casino and MOL Global, a New York Stock Exchange listed company. In 2010, Malaysia joined the US, Australia, Brunei, Canada, Chile, Mexico, New Zealand, Peru, Singapore and Vietnam in negotiating the Trans-Pacific Partnership (TPP) (Japan subsequently joined the negotiations in 2013). This agreement seeks to expand market access, strengthen intellectual property protections, and support high labour and environmental standards while fostering greater economic integration among participants. The US however has since left the TPP in 2017.

In early April 2025, the second Trump Administration imposed a 24% reciprocal tariff on Malaysian exports to the United States as part of Donald Trump's global Liberation Day tariffs. In response, Malaysian Finance Minister Amir Hamzah Azizan said that the Malaysian government would seek to resolve differences with the United States through dialogue. Malaysian Prime Minister Anwar Ibrahim said that Malaysia would not face a recession and that ASEAN would coordinate a unified response. In July 2025, the Trump administration announced plans to restrict AI chip shipments to Malaysia due to Chinese smuggling concerns. As a result of the draft US rule to ban AI chip shipments, technology stocks and construction of data centers fell in Malaysia.

In late July 2025, the Trump Administration lowered Malaysia's tariff rate from 24% to 19%, which came into effect on 5 August 2025. On 26 October 2025, the Malaysian and US governments signed a trade agreement that exempted 1,711 Malaysian products from the US tariffs regime while still maintaining the 19% tariff rate on Malaysian exports to the US. On 27 October, the two governments signed a memorandum of understanding to facilitate the development of critical minerals and rare earth minerals in partnership with US companies.

Education relations

The Fulbright English Teaching Assistant program helping improve the English language skills of thousands of Malaysian secondary school students and there is around 6,000 alumni of United States Department of State-sponsored exchange programs in Malaysia. In 2014, President Obama announced additional exchange programs, grant opportunities and fellowships for youth ages 18–35 under the Young Southeast Asian Young Leaders Initiative (YSEALI). Since 2001, the Ambassadors Fund for Cultural Preservation (AFCP) has supported 10 projects to support the preservation of cultural heritage in Malaysia.

Security co-operation and relations

Malaysia and the US enjoy strong security co-operation, with both have maintained steady defence co-operation and alliance since the 1990s. While Malaysia's security are secured by the Five Power Defence Arrangements (FPDA) with Australia, New Zealand, Singapore and the United Kingdom, the US also has military alliance with both Australia and New Zealand under the Australia, New Zealand, United States Security Treaty (ANZUS) and has established direct military and political co-operation with Singapore and Malaysia, whose armed forces were growing increasingly dependent on American arms shipments, with the M4 carbine and M16 rifle became the major assault rifles for both armed forces. Several US high-technology weapons systems also been purchased by Malaysia, notably the McDonnell Douglas F/A-18D fighter aircraft, and McDonnell Douglas MD 530G attack helicopter.
