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. As a result, India intervened in the Sri Lankan Civil War and subsequently deployed an Indian Peace Keeping Force in 1987. In the present, Sri Lanka enjoys extensive relations with China, Russia, and Pakistan.
