China says it's OK with 'paying the price' for North Korea sanctions

China will pay the biggest price from the new UN sanctions against North Korea because of its close economic relationship with the country, but will always enforce the resolutions, Chinese Foreign Minister Wang Yi said.

The UN Security Council unanimously imposed new sanctions on North Korea on Saturday over its continued missile tests that could slash the reclusive country's $3-billion US annual export revenue by a third.

Speaking at a regional security forum in Manila on Monday, Wang said the new resolution showed China and the international community's opposition to North Korea's continued missile tests, the Foreign Ministry said in a statement on Tuesday.

"Owing to China's traditional economic ties with North Korea, it will mainly be China paying the price for implementing the resolution," the statement cited Wang as saying. "But in order to protect the international non-proliferation system and regional peace and stability, China will, as before, fully and strictly properly implement the entire contents of the relevant resolution."

China, North Korea's lone major ally, has repeatedly said it is committed to enforcing increasingly tough UN resolutions on North Korea, though it has also said what it terms "normal" trade and ordinary North Koreans should not be affected.

The latest UN resolution bans North Korean exports of coal, iron, iron ore, lead, lead ore and seafood. It also prohibits countries from increasing the numbers of North Korean labourers currently working abroad, bans new joint ventures with North Korea and any new investment in current joint ventures.

"What this is going to do is send a very strong message and a united message," U.S. Ambassador to the United Nations Nikki Haley told NBC's Today in an interview on Tuesday.

Haley added that Washington would be watching to see the sanctions are enforced.

U.S. President Donald Trump praised other nations for addressing North Korea's missile programin a post on Twitter. He also shared a Fox News online story about North Korea missile preparations based on anonymous sources, despite his administration's vow to prosecute fully those who leak sensitive information.

"After many years of failure, countries are coming together to finally address the dangers posed by North Korea. We must be tough & decisive!"

Haley said Trump was keeping "all options on the table" for dealing with North Korea and speaking of its leader, Kim Jong-un, said "he has to decide if he strikes the United States, is that something he can win?"

North Korea has made no secret of its plans to develop a nuclear-tipped missile capable of striking the United States and has ignored international calls to halt its nuclear and missile programmes.

North Korea says its intercontinental ballistic missiles (ICBMs) are a legitimate means of defence against perceived U.S. hostility. It has long accused the United States and South Korea of escalating tensions by conducting military drills.

China reiterates desire for multilateral talks

Wang said that apart from the new sanctions, the resolution also made clear that the six-party talks process, a stalled dialogue mechanism with North Korea that also includes Russia and Japan, should be restarted.

China appreciated comments earlier this month by U.S. Secretary of State Rex Tillerson that the United States was not seeking to topple the North Korean government and would like dialogue with Pyongyang at some point, Wang added.

The United States did not seek regime change, the collapse of the regime, an accelerated reunification of the peninsula or an excuse to send the U.S. military into North Korea, Tillerson said.

Wang said Tillerson's "Four Nos" promise was a positive signal.

China "hopes North Korea can echo this signal from the United States", Wang added.

Speaking at the same forum on Monday, Tillerson held a door open for dialogue with North Korea saying Washington was willing to talk to Pyongyang if it halted its missile test launches.

Still, he maintained the pressure on North Korea, pressing Thailand on Tuesday for more action against Pyongyang.

North Korea said the sanctions infringed its sovereignty and it was ready to give Washington a "severe lesson" with its strategic nuclear force in response to any U.S. military action.

The successful testing of two ICBMs last month suggested the reclusive North was making technical progress, Japan's annual Defence White Paper warned.

"Since last year, when it forcibly implemented two nuclear tests and more than 20 ballistic missile launches, the security threats have entered a new stage," the Japanese Defence Ministry said in the 563-page document released on Tuesday.

"It is conceivable that North Korea's nuclear weapons programme has already considerably advanced and it is possible that North Korea has already achieved the miniaturisation of nuclear weapons and has acquired nuclear warheads," it said.

South Korea reiterated further resolutions against Pyongyang could follow if it did not pull back.

"North Korea should realise if it doesn't stop its nuclear, missile provocations, it will face even stronger pressure and sanctions," Defence Ministry spokesman Moon Sang-gyun told a regular news briefing. "We warn North Korea not to test or misunderstand the will of the South Korea-U.S. alliance."
