Burma has dropped out of the nonaligned movement to protest Cuba's tactics while hosting the nonaligned summit in Havana earlier this month, the U.S. General Assembly was told.

Burmese Foreign Minister Y. Myint Maung told the U.N. General Assembly Friday that Burma had "ended its participation in the nonaligned movement" because its delegation was "disappointed and disillusioned" by the results of the Havana conference.

The Burmese official said his delegation's proposal for a redefinition of the nonaligned movement's INVIOLABLE principles" was ignored.

Southeast Asian delegates to the conference, including the Burmese official, complained about Cuba's heavy-handed tactics in the controversy about which Cambodian delegation should be recognized.

As host and chairman of the summit that meets every three years, Cuba ruled that a "consensus" favord leaving the Cambodia seat vacant until the situation in that country is clarified.

"We have been railroaded into this decision," said Singapore's Ambassador Tommy Koh, noting that the summit never achieved a consensus.

The seat was occupied by Pol Pot's Chinese-supported delegation, but its legitimacy was questioned by Vietnam, which is backed by the Soviet Union. Viet-installed Heng Samrin in Phnom Penh as leader.
