Chinese analysts have refuted criticism that China is not acting responsibly enough to address the recent increase in tensions on the Korean Peninsula.

It is evident that China is actively making diplomatic efforts to ease the tensions and pushing for contacts and talks among relevant parties, they said, adding that these facts should not be ignored.

John McCain, a senior U.S. senator, said China "is not behaving as a responsible world power" in dealing with the Korean Peninsula situation.

The U.S. House of Representatives Committee on Foreign Affairs and the House Armed Services Committee have called on China to suspend economic and energy assistance to the Democratic People's Republic of Korea (DPRK) to show the DPRK consequences for its "aggression."

China does not control the DPRK, and China's actions are made out of a respect for other sovereign states and humanitarian considerations, said Zhu Feng, professor at Peking University's School of International Studies.

United Nations Security Council Resolution 1874 adopted in June 2009 made it clear measures imposed by the resolution upon the DPRK "are not intended to have adverse humanitarian consequences for the civilian population of the DPRK."

"There is serious misunderstanding and hostility between the DPRK and the Republic of Korea (ROK). The best solution is to make every possible effort to bring the parties to negotiation to maintain peace," Zhu said.

"Only with more contact and dialogue can we ease the current tensions and find a solution acceptable to all," Zhu added.

As tensions grow, China has proposed emergency consultations be held next month between the heads of the delegations to the Six-Party Talks, Wu Dawei, Chinese special representative for the Korean Peninsula affairs, said Sunday.

The analysts also called for calm and restraint to maintain and promote peace and stability on the Korean Peninsula.

The series of large joint military drills between the ROK and the United States in the Korean Peninsula region is unprecedented, and the show of force may sting the DPRK and heighten tensions, said Tao Wenzhao, a research fellow at the Institute of American Studies at the Chinese Academy of Social Sciences (CASS).
