Foreign relations of Sri Lanka refers to the diplomatic and commercial relations between Sri Lanka and other countries. Sri Lanka has stressed its principle of "friendship towards all, enmity towards none" in its diplomacy.

Since the 1950s, Sri Lanka has followed a non-aligned foreign policy, which does not take sides with major powers.Patrick Peebles, The History of Sri Lanka (Greenwood, 2005), p. 118. Since the end of the Cold War in Asia, the country has pursued better relations with all major powers and seeks to strengthen its diplomatic, economic and military ties with China, India, Pakistan, Russia, the United States, Japan, South Korea and the European Union. Sri Lanka has also forged close ties with the member states of the Association of Southeast Asian Nations (ASEAN), African Union and Arab League.

Sri Lanka participates in multilateral diplomacy, particularly at the United Nations, where it seeks to promote sovereignty, independence, and development in the developing world. Sri Lanka was a founding member of the Non-Aligned Movement (NAM). It also is a member of the Commonwealth of Nations, South Asian Association for Regional Cooperation (SAARC), World Bank, International Monetary Fund (IMF), Asian Development Bank (ADB), Shanghai Cooperation Organisation (as dialogue partner) and the Colombo Plan. Sri Lanka continues its active participation in the NAM, while also stressing the importance it places on regionalism by playing a strong role in SAARC.

History The goal of Sri Lanka's foreign policy is to maintain a strong, independent, powerful and unitary Sri Lanka, whose foreign policy establishment maintains it in achieving that goal.

Sri Lanka's foreign policy has been founded in the national interest. In a period of rapid and continuing change, foreign policy can respond optimally to new challenges and opportunities. It has to be an integral part of the larger effort of building the nation's capabilities through economic development, strengthening social fabric and well-being of the people and protecting Sri Lanka's sovereignty and territorial integrity. Sri Lanka's foreign policy is a forward-looking engagement with the rest of the world, based on a rigorous, realistic and contemporary assessment of the bilateral, regional and global geo-political and economic milieu.

Military The Sri Lanka Armed Forces are the overall unified military of Sri Lanka and encompass the Sri Lanka Army, Navy, and Air Force, which come under the Ministry of Defence (MOD). They receive military support mainly from China, Russia, India, Pakistan and Israel. The United States also gives limited support.
