Washington, United States (Reuters): Washington pushed Beijing to keep pressure on North Korea to return to talks to halt Pyongyang from making further advances in its weapons program in violation of U.N. resolutions.

According to China's Commerce Ministry, it would suspend all imports of coal from North Korea starting Feb. 19. The announcement came as part of Beijing 's efforts to implement international sanctions against the country.

Earlier this month, Pyongyang tested an intermediate-range ballistic missile, its first direct challenge to the international community since U.S. President Donald Trump took office on Jan. 20.

President Trump's administration has said that China should do more to pressure Pyongyang.

A State Department spokesperson said, referring to North Korea , "All countries should fully and transparently implement all relevant UN Security Council Resolutions on the DPRK."

"We continue to urge China to exert its unique leverage as North Korea 's largest trading partner to convince Pyongyang to return to serious talks on denuclearization."

China's Ministry of Commerce has said its ban on coal imports from North Korea would be effective until Dec. 31.

China announced in April last year that it would ban North Korean coal imports to comply with sanctions imposed by the United Nations and aimed at starving the country of funds for its nuclear and ballistic missile programs.

But it made exceptions for deliveries intended for "the people's well-being" and not connected to the nuclear or missile programs.
