China is committed to a denuclearized Korean Peninsula and hopes that peace and stability will be maintained, Premier Li Keqiang said on Friday.

Parties involved in the peninsula issue should be patient and seize opportunities, especially positive factors to promote dialogue, Li told a news conference in Beijing.

It is especially important for relevant parties to promote dialogue between Pyongyang and Washington toward outcomes that all would like to see, Li said.

The issue is long standing and complicated, and cannot be resolved overnight, he added.

The Democratic People's Republic of Korea and the United States have expressed a readiness to stay engaged with each other after the Hanoi Summit, which is better than no contact at all, he said.
