BEIJING (Reuters) - China shares the region's "serious concerns" about a nuclear North Korea and urged all parties to keep negotiating, a senior Chinese military officer said Wednesday after talks with Pentagon officials.

Lieutenant-General Ma Xiaotian did not announce any new measures against Pyongyang, but said Beijing was concerned about North Korea, which staged a second nuclear test on May 25, prompting new U.N. sanctions.

"For the regional security of northeast Asia, the North Korean nuclear issue is not only a serious concern for the United States and neighboring South Korea a

BEIJING (AP) — The Chinese and U.S. militaries will work together to avoid confrontations at sea that have sparked worries of a crisis in overall relations, a top Chinese military officer said Wednesday.

The issue was at the center of their first high-level military talks in 18 months after a series of recent naval encounters — including a collision of a Chinese submarine and a U.S. sonar device — that have raised concerns about poor communication between the two sides.

WASHINGTON (AFP) — China has given its word to the United States that it is "deeply committed" to implementing tough new nuclear sanctions against North Korea, a senior US official said Friday.

The official also said that as part of the effort to put a straitjacket on Pyongyang after its latest nuclear test and missile launches, Washington had set up an inter-agency team to coordinate the sanctions with other nations.

"They are certainly saying quite strenuously that they are deeply committed to full implementation of the provisions that are in the resolution," the senior administration official said, referring to China.
