The Chinese Foreign Ministry on Friday urged restraint on all sides in the rapidly escalating North Korean weapons crisis following Pyongyang's threat to test a hydrogen bomb in the Pacific Ocean.

Speaking at a regular press conference in Beijing, ministry spokesman Lu Kang also said that China opposes unilateral sanctions outside the United Nations framework.

He was commenting on North Korean Foreign Minister Ri Yong Ho's remark to reporters in New York Thursday that his country may conduct a hydrogen bomb test in the Pacific Ocean as one of its "highest-level" actions threatened by the country's leader Kim Jong Un against the United States.

Earlier Thursday, U.S. President Donald Trump ordered fresh unilateral sanctions taking aim at North Korea's nuclear and ballistic missile programs by sanctioning banks, other entities, or individuals that trade with the country.

Lu also took issue with Trump's claim that China's central bank has ordered Chinese banks to immediately stop doing business with North Korea, saying it "differs from the actual facts."

Trump said at the United Nations that "China, their central bank has told their other banks...to immediately stop doing business with North Korea."
