The leader of Cambodia’s main opposition party, Kem Sokha, was arrested early Sunday at his home and accused of treason for participating in what the government said was a Washington-backed plot to undermine the country’s leadership.
A top official for Human Rights Watch in Asia called the arrest a “disastrous setback” for Cambodia as its long-ruling authoritarian prime minister, Hun Sen, consolidates power in advance of elections scheduled for next year and marked a further deterioration in its relations with the United States.
