BEIJING, June 20 -- China will work with the United States for positive results at the first diplomatic and security dialogue, to be held on Wednesday in Washington D.C., a Foreign Ministry spokesperson said here Tuesday.

Foreign Ministry spokesperson Geng Shuang made the remarks in response to a question concerning a briefing on the dialogue by U.S. State Department on Monday, which said that the U.S. side would mainly discuss the Korean Peninsula nuclear issue, maritime and counter-terrorism issues with China.

Geng said China's stance on the Korean Peninsula nuclear issue has been clear and consistent.

China is committed to the denuclearization of the Korean Peninsula, resolving the issue through dialogue and negotiation and ensuring regional peace and stability, said Geng.

He called on parties concerned to assume their due responsibilities and work for an appropriate resolution of the issue.

"China is willing to maintain communication and cooperation with the United States and relevant parties on the issue," said Geng.

On the South China Sea issue, Geng said the situation of the South China Sea is stabilizing and has returned to the track of peaceful negotiation, thanks to the joint efforts of China and countries from the Association of Southeast Asian Nations (ASEAN).

"China hopes relevant parties will respect the efforts made by regional countries to resolve disputes via consultation and contribute more to regional peace and stability," said Geng.

On the counter-terrorism issue, Geng said it is in the interests of both China and the United States to boost cooperation in the area as both are victims of terrorism.

China hopes that both sides could exchange views on the fight against terrorism in the principle of mutual respect, equality and mutual benefit, he said.

Chinese State Councilor Yang Jiechi will co-chair the dialogue with U.S. Secretary of State Rex Tillerson and Secretary of Defense James Mattis.

Fang Fenghui, a member of China's Central Military Commission (CMC) and chief of the CMC Joint Staff Department, will also participate.

The diplomatic and security dialogue is one of four high-level mechanisms established during the Mar-a-Lago meeting between Chinese President Xi Jinping and U.S. President Donald Trump in Florida in April.

The other three are dialogues on economics; law enforcement and cyber security; and on social, cultural and people-to-people exchange.
