China Thursday reaffirmed its stance on the sinking of the Republic of Korea's frigate "Cheonan," saying it will keep communicating with the parties concerned.

"We have clearly declared our stance on the ship sinking many times. We hope relevant parties deal with the incident appropriately, in consideration of peace and stability on the Korean Peninsula," Foreign Ministry spokesman Qin Gang told a regular press briefing.

Qin said the incident is still being discussed by the United Nations Security Council.

On March 26, the ROK Navy frigate "Cheonan," with 104 crew members onboard, went down off the ROK island of Baekryeong off the west coast due to an unexplained explosion. Forty-six sailors were killed.

Seoul said after completing an investigation that the warship was torpedoed by the Democratic People's Republic of Korea (DPRK). But Pyongyang has denied its involvement in the incident.

After the frigate sank, ROK June 4 delivered a letter formally requesting the UN Security Council to take action over the sinking of its ship. The Security Council has not reached any conclusion on the issue yet.
