China's top nuclear envoy will visit South Korea this week to discuss North Korea's nuclear and missile threats and also meet with presidential candidates to get a glimpse into the policy direction going forward, diplomatic sources in Seoul said Sunday.
Wu Dawei will come to Seoul on Monday for a five-day stay during which he plans to meet his South Korean counterpart Kim Hong-kyun and discuss their cooperation against the North's repeated provocations including a possible nuclear test, South Korea's news agency (Yonhap) reported, citing the Foreign Ministry.
Their meeting will mark the first time since they held talks in Beijing in December. The meeting comes amid speculation that the North may carry out a major provocation including an additional nuclear test. In the latest provocation, the North fired a ballistic missile from its eastern port of Sinpo into the East Sea. 
China's top nuclear envoy may also deliver his country's opposition to the installation of the missile defense system, called the Terminal High Altitude Area Defense (THAAD). Less important in his trip to Seoul might be to have chances to meet presidential hopefuls, diplomatic sources said. His meetings might be aimed at discussing key issues involving the two countries with the possible future leader of South Korea before the May 9 presidential election to fill the void left by the ouster of former president Park Geun-hye.
