Prime Minister Shinzo Abe and U.S. President Donald Trump held a 35-minute teleconference Thursday morning, agreeing to jointly deal with the military threat of North Korea after it fired a ballistic missile into the Sea of Japan a day before.

The two leaders also agreed Beijing should take more action to persuade Pyongyang to stop its nuclear weapons and missile programs beyond just halting imports of coal from North Korea, a senior Japanese official told reporters.

"China has already taken action concerning its coal imports. But they agreed that is not sufficient," the official said during a media briefing about the Trump-Abe conversation.
