US and China to co-operate on North Korea nuclear tests
April 1, Washington: China and the United States will work together to try and prevent further missile tests by North Korea, US President Barack Obama said.
In recent weeks, North Korea has carried out a hydrogen bomb test and has repeatedly test-fired missiles while making threats to the West.
Obama met Chinese President Xi Jinping on the sidelines of a nuclear summit in Washington on Thursday. He said both countries were keen to see a nuclear-free Korean peninsula.
He said he and Xi were seeking to agree "how we can discourage action like nuclear missile tests that escalate tensions and violate international obligations".
Xi, quoted by China's state news agency Xinhua, said it was critical all parties "fully and strictly" implemented newly-agreed sanctions. China is North Korea's closest ally and largest trading partner.
Zheng Zeguang, China's assistant foreign minister, said the presidents had a "candid and in-depth exchange of views on a variety of issues...and reached an important consensus". He called the meeting "positive, constructive and fruitful".
North Korea's nuclear test on 6 January and a satellite launch on 7 February were violations of existing UN sanctions.
Since then, the UN and Washington passed further sanctions on Pyongyang. The UN steps were drafted with support by China and reportedly came after two months of negotiations between Beijing and Washington.
