A high-ranking Chinese diplomat will visit Japan this week to prepare for President Xi Jinping's visit to the country in June.
Japan's Foreign Ministry announced on Monday that Chinese Communist Party Political Bureau member Yang Jiechi will arrive for a three-day visit on Thursday.
Yang is scheduled to hold talks with the head of Japan's National Security Secretariat Shotaro Yachi.
Ministry sources say that during talks in the resort town of Karuizawa on Thursday, Yachi and Yang are expected to make preparations for Xi's visit to Japan for the G20 summit in Osaka late next month.
Arrangements are also underway for Yang to meet with Prime Minister Shinzo Abe and Foreign Minister Taro Kono. They would be expected to exchange views on regional issues such as North Korea, and trade friction between China and the United States.
