USA calls on China to get tough with North Korea

The two leaders also reached a consensus that South Korea and Japan should work together with the U.S., China and Russian Federation to deal with the North Korean nuclear issue, the presidential office said.

“We urge South Korea to exercise restraint”, British Foreign Secretary Philip Hammond said during a visit to Japan, after the South resumed the broadcasts.

Seoul turned off its speakers in August after marathon negotiations with the North. Seoul also limits the entry of some South Koreans to an industrial park in North Korea jointly run by the two Koreas, which has been a valuable cash source for the North.

North Korea called the device the “H-bomb of justice”, but its state news agency also said it would act as a responsible nuclear state and would not use its nuclear weapons unless its sovereignty was infringed.

The United Nations has already promised to tighten sanctions on Pyongyang.

So far no radiation has been detected by China, Japan or South Korea, it could take many more days to collect, maybe weeks to analyze with no guarantee of success.

Its prime minister, Shinzo Abe, agreed with U.S. President Barack Obama in a telephone call that a firm global response was needed, the White House said. Chinese Foreign Ministry spokeswoman Hua Chunying, asked on Friday what China’s position was on the need for a peace treaty, said China supported resolving all parties “reasonable concerns” and achieving lasting peace through the so-called six party talks.

Washington has said it will not accept North Korea as a nuclear-armed state and will continue to pile on diplomatic and economic pressure until Pyongyang backs down.

“We have to face the reality that sanctions alone will not leverage the North Korean policy in the absence of a fundamental change in Chinese policy”, DeThomas said. But he added: “Nothing that has occurred in the last 24 hours has caused the United States government to change our assessment of North Korea’s technical and military capabilities”.

South Korean officials said stopping the broadcasts was the main reason the North agreed at that time to end an armed standoff and express regret over a landmine explosion that injured South Korean soldiers.

The leader gained much popularity this year when North Korea experimented a “Hydrogen bomb” early this week and shocked the world leaders.

As per to the estimate, the latest weapon is much more unsafe than any atomic bomb ever tested on the earth.

The DPRK announced Wednesday that it had successfully carried out its first hydrogen bomb test. China was not notified of the test beforehand, Hua told reporters Wednesday.
