SOUTH Korean President Moon Jae-in has called on his US allies to help prevent a war, amid worsening tension over the North’s nuclear threat.

Trump has repeatedly claimed that China could easily pressure North Korea into curtailing its missile and nuclear programs. He raised the issue again in tweets Saturday.

North Korea has test-fired a ballistic missile, the South Korean military quoted by Yonhap news agency says.

The US is open to negotiations with North Korea aimed at removing nuclear weapons from the region, Secretary of State Rex Tillerson has said.
