MOSCOW, Sept. 11 (Xinhua) -- Russian President Vladimir Putin and German Chancellor Angela Merkel reaffirmed on Monday that they uphold peaceful ways to resolve the Korean Peninsula impasse.

During a phone conversation, the two leaders agreed that "the settlement of this acute crisis is possible only by political and diplomatic means, by resuming negotiations of all parties involved," according to a Kremlin statement.

Russia and Germany will continue discussion of the Korean Peninsula situation at the level of foreign ministers, it said.

According to the Kremlin, Putin and Merkel strongly condemned the Democratic People's Republic of Korea (DPRK)'s disregard of the relevant resolutions of the United Nations Security Council.

They said that Pyongyang's nuclear and missile activities, which are contrary to the principles of global non-proliferation, pose a serious threat to regional peace and security.

The DPRK claimed earlier this month that it successfully detonated an H-bomb, which can be carried by an intercontinental ballistic missile. The sixth nuclear test has incurred worldwide criticism.
