By Beijing has called for "constructive efforts" to ease the Korean peninsula situation after the Democratic People's Republic of Korea top leader Kim Jong-un reportedly announced that his country has the capability to detonate a hydrogen bomb.

The DPRK has turned into "a powerful nuclear weapons state ready to detonate self-reliant A-bomb and H-bomb to reliably defend its sovereignty and the dignity of the nation," the official KCNA news agency, quoting Kim, reported on Thursday.

Kim made the remarks while inspecting a historical military site. Previously the DPRK said its pursuit of nuclear weapons is an outcome of the hostile US policy toward it.

In response, Foreign Ministry spokeswoman Hua Chunying told a news conference on Thursday in Beijing that China has consistently upheld achieving denuclearization of the Korean Peninsula, safeguarding Peninsular peace and stability and resolving issues through dialogue and reconciliations.

All the relevant parties are expected to “make constructive efforts” to do more to help ease the situation and to achieve an early restart of the Six-Party talks, Hua said.
