In foreign affairs Lini joined the Non Aligned Movement, opposed Apartheid in South Africa and all forms of colonialism, established links with Libya and Cuba, and opposed the French presence in New Caledonia and their nuclear testing in French Polynesia. Opposition to Lini's tight grip on power grew and in 1987, after he had suffered a stroke whilst on a visit to the United States, a section of the Vanua'aku Pati (VP) under Barak Sopé broke off to form a new party (the Melanesian Progressive Party, MPP), and an attempt was made by President Ati George Sokomanu to unseat Lini. This failed, and Lini became increasingly distrustful of his VP colleagues, firing anyone he deemed to be disloyal.
