China and South Korea against war on Korean peninsula

The crisis over North Korea's weapons programmes must be resolved through talks, not war, Chinese President Xi Jinping said on Thursday.

Xi made the comments to visiting South Korean President Moon Jae-in a day after the UN Secretary-General Antonio Guterres warned of the danger of "sleepwalking" into conflict over North Korea's nuclear ambitions.

On Tuesday, US Secretary of State Rex Tillerson offered to begin direct talks with North Korea without pre-conditions.

But the White House said on Wednesday that no negotiations could be held until North Korea improved its behaviour.

Russian President Vladimir Putin said Tillerson's offer of direct contacts with North Korea was "a very good signal" while warning that any US strike on the country would have catastrophic consequences.

Putin and US President Donald Trump discussed North Korea during a phone call, the White House and Kremlin said in separate statements. 

The two leaders talked about "working together to resolve the very dangerous situation," the White House said on Thursday.

Tillerson is to attend a UN Security Council ministerial meeting on North Korea in New York on Friday at which he plans to urge countries to maintain a US-led campaign to pressure Pyongyang to abandon its weapons programs through sanctions.

North Korea tested its most advanced intercontinental ballistic missile on November 29, which it said could put all of the US within range, in defiance of international pressure and UN sanctions.

The US has said all options were on the table in dealing with North Korea, including military action.

Dialogue and consultation

Meeting in Beijing's Great Hall of the People, Xi told Moon the goal of denuclearising the Korean peninsula must be stuck to, and war and chaos cannot be allowed, Chinese state media said.

"The peninsula issue must, in the end, be resolved via dialogue and consultation," Xi was cited as saying.

China and South Korea have an important shared interest in maintaining peace, and China was willing to work with South Korea to promote talks and support North and South to improve relations, Xi said.

South Korea's Yonhap news agency said Xi and Moon agreed war on the peninsula would not be tolerated and they would cooperate in applying sanctions and pressure on North Korea.

The apparently warm tone of their talks followed nearly a year of tense relations between the two countries.

THAAD issue

China has been furious about the deployment of the US-made Terminal High Altitude Area Defence (THAAD) anti-missile system in South Korea, saying its powerful radar can see far into China.

China and South Korea agreed in October to normalise exchanges and move past the dispute, which froze trade and business exchanges.

Xi reiterated China's position on THAAD and said he hoped South Korea would continue to "appropriately handle" the issue.

Guterres, speaking to reporters in Tokyo after meeting Japanese Prime Minister Shinzo Abe, said Security Council resolutions on North Korea's nuclear and missile programmes must be fully implemented by Pyongyang and other countries.

He said he expected Friday's Security Council meeting would deliver a strong expression of unity and the need for diplomacy to resolve the issue.

"The worst possible thing that could happen is for us all to sleepwalk into a war," he said.

British Foreign Secretary Boris Johnson said after meeting Japanese Foreign Minister Taro Kono in London on Thursday that military options in North Korea did not look attractive and the best way forward was to intensify economic pressure.

Both China and Russia have welcomed Tillerson's apparent overture.

Putin said a US strike on North Korea would have catastrophic consequences and that he hoped to work with Washington eventually to resolve the crisis.

Putin told a news conference that Russia did not accept North Korea's nuclear status, but some US actions had provoked North Korea.

"We believe the two sides should now stop aggravating the situation," he said.

North Korea justifies its weapons programmes as necessary defence against US plans to invade. The US, which has 28,500 troops in South Korea, a legacy of the 1950-53 Korean war, denies any such intention.

"Act of war"

North Korea's state news agency KCNA said Trump was taking a big step towards nuclear war in seeking a naval blockade and North Korea would take "merciless self-defence" measures if the US tried to impose one.

North Korea would regard a naval blockade as "an act of war" and a "wanton violation" of its sovereignty and dignity, the agency cited a Foreign Ministry spokesman as saying, while reiterating that North Korea was a responsible nuclear power that would fulfil its non proliferation commitments.

It was not immediately clear if the latter remark was a response to Tillerson's statement this week that Washington could not accept Pyongyang as a nuclear power as it was a proliferation risk.

Washington has not publicly called for a blockade of North Korea, but has sought tougher UN steps, including non-consensual inspections of shipping to North Korea.

Stepped-up UN Security Council sanctions imposed in September after North Korea's sixth nuclear test called on states to inspect vessels on the high seas, with the consent of the flag state, if they had reasonable grounds to believe the ships were carrying prohibited cargo.

A tougher US-drafted resolution was watered down to win the support of Russia and China.
