It calls for concerted efforts of all parties to work toward the same direction on the Korean Peninsula nuclear issue, said the China's Foreign Ministry spokesperson on a press conference Tuesday.

"Realizing denuclearization of the peninsula and safeguarding peace and stability there are not just China's business, but need concerted efforts from all parties," Foreign Ministry spokesperson Hua Chunying said.

Hua was asked to respond to some U.S. officials' remarks against China on the Korean nuclear issue.

As a close neighbor to the Korean Peninsula and a responsible major power, China has been making unremitting efforts and playing an important role, according to Hua.

However, realizing denuclearization on the Korean Peninsula and safeguarding the peace and stability of the Peninsula cannot rely solely on China, Hua added.

Hua pointed out that some parties' failure to do so is one major reason why the denuclearization process on the Peninsula has run into difficulties and the Six-Party Talks are temporarily on hold.

China hopes and urges that the relevant parties earnestly fulfill their due responsibilities and play a constructive role. They should work with China to bring the Korean nuclear issue back to the right track, instead of pointing fingers and making inappropriate remarks.
