WASHINGTON (AP) — China's ambassador says the US shouldn't obstruct efforts by China and its neighbors to agree on a code of conduct in the disputed South China Sea.

Ambassador Cui Tiankai (SWAY TEE-EHN K-EYE) says the US has no territorial claim in those waters and should let countries in the region manage their disputes in a "friendly and effective way."

Beijing's island-building in the South China Sea has drawn criticism from Washington.

President Donald Trump departs later this week on a five-nation trip to Asia that includes a state visit to China.

The ambassador said North Korea will be a priority in talks between the Chinese and US presidents.

Cui warned that tensions over the North's nuclear program could get more dangerous without more efforts to reach a negotiated solution.
