Rex Tillerson urged to be 'cool-headed' over North Korea
China's Foreign Minister Wang Yi has urged the US to remain "cool-headed" over North Korean tensions.
The situation was at a "crossroads", but must not be allowed to develop into a conflict, he said after hosting US Secretary of State Rex Tillerson. Mr Tillerson spoke of "dangerous levels" of tension, a day after suggesting the US might launch a pre-emptive strike against North Korea. North Korea is working to develop nuclear missiles that can reach the US. Last week, it launched four ballistic missiles - defying United Nations resolutions. Mr Tillerson is in Beijing in the final leg of his East Asia tour, which has been dominated by anxieties over North Korea. In South Korea on Friday, he said a US military response would be on the table if North Korea threatened South Korea or US forces. President Donald Trump tweeted that North Korea was "behaving very badly". He added that China - Pyongyang's main ally - had done "little to help". Mr Wang defended the Chinese position, saying all parties were duty-bound to implement UN sanctions against Pyongyang, but also to seek dialogue and diplomatic solutions. "We hope that all parties, including our friends from the United States, could size up the situation in a cool-headed and comprehensive fashion and arrive at a wise decision," Mr Wang said. Mr Tillerson did not repeat his threat in Beijing, but stressed that the US and China shared "a common view that tensions on the peninsula are quite high right now - and that things have reached a rather dangerous level". He added, however, that they had both committed "to do whatever we can to prevent any kind of conflict breaking out". The US has deployed its Terminal High-Altitude Area Defense system (Thaad) in South Korea in a move it says is designed to protect against threats from North Korea. But China has claimed the system goes "far beyond" the defence needs of the Korean peninsula. Mr Tillerson, a former oil executive with no prior diplomatic experience, will meet Chinese President Xi Jinping on Sunday. Mr Xi is scheduled to visit the United States next month for his first meeting with President Trump. Some commentators expect Mr Tillerson to downplay any tensions between the two countries ahead of that encounter. Muted language: Analysis by Carrie Gracie, China editor, Beijing For America's top diplomat, this was a first attempt at tackling one of the thorniest problems in one of diplomacy's most delicate relationships. So in Beijing today, Mr Tillerson kept it diplomatic. There was no public repetition of President Trump's complaint that China is not doing enough to prevent North Korea's nuclear and missile programmes. Instead Mr Tillerson focussed on a point of agreement with his Chinese hosts. Chinese Foreign Minister Wang Yi showed the same restraint. Earlier this month, he said the US and North Korea were like trains accelerating towards a head-on collision. But today he framed the choices in milder language. A lot now hangs on whether the two presidents can tackle a daunting array of disputes and build the kind of personal trust which might help them inch towards a solution for the Korean peninsula.
