The Zheng He became the first Chinese warship to dock in Cambodia when it arrived Wednesday, signalling deeper military cooperation between the two nations. The ship, which carries more than 400 personnel, will remain at Sihanoukville until the weekend, said a Chinese embassy statement after the Zheng He docked in Cambodia's main seaport. The visit is intended to boost "the good relationship" between Phnom Penh and Beijing, Chinese officials said.
