HANOI (AFP) - Vietnams legislature on Saturday rejected a proposed 56-billion-dollar bullet train, after concerns that more basic needs should take priority over a project dismissed as economically unsound. In a rare decision by the communist-dominated National Assembly, which usually backs proposals from the government, deputies said they asked for further study of the plan. The National Assembly did not approve a resolution on this project, one deputy, Duong Trung Quoc, told AFP after the vote, which was closed to foreign reporters. He said a slight majority of 20-30 deputies voted against the plan. Under the communist governments proposal, the train would have linked the capital Hanoi with the southern commercial hub of Ho Chi Minh City 1,570-kilometres (975 miles) away, at speeds of 300 kilometres an hour. On the countrys existing single-track railway, the journey now takes almost two days. Plans called for the high-speed link to be built by 2035 at a cost of 56 billion dollars, almost 60 percent of the countrys gross domestic product (GDP) last year. Although more than 90 percent of the nearly 500 deputies are Communist Party members, they have in recent years become more vocal over the countrys major problems.
