Chinese Foreign Minister Wang Yi on Wednesday reiterated Beijing's commitment to denuclearizing North Korea, days after the top U.S. military commander in South Korea said Pyongyang may be able to miniaturize a nuclear weapon to load it atop a missile. 

"We are firmly committed to denuclearizing the Korean Peninsula and maintaining peace and stability on the Korean Peninsula," Wang said in his speech at the Chinese foreign ministry, which details the agenda of an upcoming APEC summit in Beijing. 

Wang said China pursues a "common, comprehensive, cooperative and sustainable Asian security vision" that will be accepted by all countries in Asia. China is gearing up to host the APEC summit next month. 

North Korea is not an APEC member, but its nuclear weapons drive has been a topic of the annual summit. 

Last week, Gen. Curtis Scaparrotti, the top commander of U.S.

forces in South Korea, told reporters in Washington that he "believes" that North Korea has the capabilities to build nuclear-tipped missiles, although he has no evidence to confirm his assumption. 

North Korea has conducted three nuclear tests since 2006, including the most powerful one in February last year. 

The six-party talks, involving South Korea, North Korea, the U.S., China, Russia and Japan, were last held in December 2008.

North Korea has conducted two more nuclear tests since then.

North Korea wants an unconditional resumption of the six-party talks, but South Korea and the U.S. demand that Pyongyang first take concrete steps to show its denuclearization commitment. (Yonhap)
