Russian President Vladimir Putin discussed the crisis on the Korean Peninsula in the telephone talks with South Korea's new president, Moon Jae-in, during which the sides emphasized importance of the diplomatic settlement of the crisis, the Kremlin press service said in a statement Friday.
"Moon will send a delegation headed by Park Byeong-seug, a veteran member of parliament and a senior official of Moon's liberal Democratic Party".
"During the telephone call, Moon told Xi that he "understands China's interest in the THAAD deployment and its concerns", Yoon said". China's foreign ministry didn't immediately respond to a request for comment.
The delegation will leave for Beijing on Saturday to join the forum, another government official said earlier in the day. "We chose to send a delegation comprised of Rep. Park and other government officials".
Park, who also served as co-chairman of Moon's presidential campaign team, is expected to meet Chinese officials on the sidelines of the forum to discuss the ways to fix relations, the official told Yonhap. Beijing did not give details, but Yonhap said that it would be led by Kim Yong-jae, the North's minister of external economic relations.
Moon's predecessor, Park Geun-hye, who was impeached and ousted as president, had agreed to the deployment of THAAD, saying that it was needed to protect South Korea against a growing ballistic-missile threat from North Korea.
North Korea accused the US and South Korean security agencies of planning a biochemical attack on leader Kim during April 15 celebrations in the North's capital of the anniversary of the birth of state founder Kim Il Sung.
South Korea's new President Moon Jae-in is one of the leading figures in the pro-democracy movement which led to South Korea's first democratic election in 1987.
China has invited South Korea to a summit on a global trade initiative in Beijing in what appears to be the latest move to fix a strained relationship and reach out to the new South Korean president.
Moon also expressed hopes the two countries would be able to cooperate in developing East Asia, including extending a natural gas pipeline from Siberia to South Korea, the Blue House said.
