Report: Chinese nuclear envoy in North Korea

SEOUL, March 17 (UPI) -- The top Chinese negotiator on North Korea's nuclear program was in Pyongyang Monday, a day after North Korea fired 25 missiles toward the East Sea.

The official Korean Central News Agency reported the visit of Chinese envoy Wu Dawei in the North Korean capital, but gave no details on when he arrived or who he was meeting with.

Word of Wu's presence in North Korea came a day after South Korea's Yonhap News Agency reported North Korea fired 25 short-range, surface-to-surface missiles Sunday in a show of force during joint South Korean-U.S. military drills.

Ten missiles were fired toward the East Sea within a 10-minute period early Sunday evening, and eight more within five minutes Sunday night, followed by seven rockets in a four-minute period. All of the missiles landed in international waters after traveling about 46 miles, South Korea's Joint Chiefs of Staff said.

"The rockets were fired from [North Korea's] east coastal region near Wonsan and flew eastward," the military leaders said in a statement. "We call on North Korea to stop further provocative actions."

South Korean troops are conducting joint combat field training exercises with 7,500 U.S. troops until April 18, Yonhap said.
