started as soon as the People's Republic of China was formed in 1949. The two countries signed an important Rice-Rubber Pact in 1952. Sri Lanka played a vital role at the Asian–African Conference in 1955, which was an important step in the crystallisation of the NAM. The Bandaranaike government of 1956 significantly changed the pro-western policies set by the previous UNP government. It recognised Cuba under Fidel Castro in 1959. Shortly afterward, Cuba's revolutionary Che Guevara paid a visit to Sri Lanka. The Sirima-Shastri Pact of 1964 and Sirima-Gandhi Pact of 1974 were signed between Sri Lankan and Indian leaders in an attempt to solve the long-standing dispute over the status of plantation workers of Indian origin. In 1974, Kachchatheevu, a small island in Palk Strait, was formally ceded to Sri Lanka. By this time, Sri Lanka was strongly involved in the NAM, and the fifth NAM summit was held in Colombo in 1976. The relationship between Sri Lanka and India became tense under the government of J. R. Jayawardene.

In the present, Sri Lanka enjoys extensive relations with China, Russia, and Pakistan. Military The Sri Lanka Armed Forces, comprising the Sri Lanka Army, the Sri Lanka Navy, and the Sri Lanka Air Force, come under the purview of the Ministry of Defence. The total strength of the three services is around 346,000 personnel, with nearly 36,000 reserves. Sri Lanka has not enforced military conscription. Paramilitary units include the Special Task Force, the Civil Security Force, and the Sri Lanka Coast Guard. Since independence in 1948, the primary focus of the armed forces has been internal security, crushing three major insurgencies, two by Marxist militants of the JVP and a 26-year-long conflict with the LTTE. The armed forces have been in a continuous mobilised state for the last 30 years.
