South Korean President Moon Jae-In began his first state visit to China on Wednesday to soothe relations strained by the US deployment of an anti-missile system that has angered Beijing.

　　韩国总统文在寅于周三开始了他的首次对华国事访问，以期缓和由于美国部署反导系统造成的紧张关系，此举已经激怒北京。

　　Moon is also expected to discuss the North Korean nuclear crisis during his four-day trip, which includes talks with Chinese President Xi Jinping on Thursday.

　　预计文在寅将会在他的四天行程中讨论朝鲜核危机，包括于周四与中国主席交谈。

　　The US military installed the powerful THAAD (Terminal High Altitude Area Defense) system in the South earlier this year to guard against threats from the nuclear-armed North.

　　But last month, the two countries issued identically-worded statements on their mutual desire to improve relations.

　　It did not state any specifics, but Beijing has demanded that Seoul formally promise not to deploy any more THAAD launchers and not to join any regional US missile defence system.

　　它并未提及细节，但是北京已经要求首尔正式承诺，不部署更多萨德发射器，不参与美国的任何地区防导系统。

　　Moon’s office said ahead of the trip that the president, who took office in May, wanted to "normalise" ties with Beijing, and that the visit would be a turning point towards a "more mature" relationship.

　　文在寅的办公室在此行前表示，于五月上台的总统希望与北京的关系“正常化”，访问将会是发展“更成熟”关系的一个转折点。
