The United States said Wednesday it will bar entry to Cambodians who undermine their country’s democracy and called on the government to reverse a crackdown on the opposition. Cambodia’s highest court outlawed the country’s main opposition party last month and banned its MPs from politics, in a move that critics say will deliver a body blow to democracy in the Southeast Asian kingdom. While China supports the Cambodian government economically, by reducing Phnom Penh’s reliance on Western aid and loans, Russia is offering to lend certain moral support for the clampdown, writes David Hutt for the Asia Times.
