The UN Security Council has unanimously condemned North Korea's latest missile test and warned of new sanctions.
In a statement, the 15-member Council demanded that Pyongyang conduct no further such tests.
North Korea earlier said the missile it had tested on Sunday was a new type of rocket capable of carrying a large nuclear warhead.
The missile travelled some 700km (435 miles), reaching an altitude of 2,000km and landing in the sea west of Japan.
North Korea said it was a test of the abilities of a "newly developed ballistic rocket".
China has called for "restraint" after North Korea's latest missile test, warning against ramping up tensions in the region.
The missile flew more than 700km before landing in the Sea of Japan (East Sea) surrounded by the Korean peninsula, Japan and the Russian far east.
China said it opposes North Korea's "violation of the (UN) Security Council's resolutions", and China has been undergoing pressure from the USA to help stop the missile tests.
Russian President Vladimir Putin and Chinese counterpart Xi Jinping expressed concern about rising tensions on the Korean peninsula. An EU spokesperson said that the test-firing of the ballistic missile constitutes a "threat to international peace and security".
US President Donald Trump called for tougher sanctions against Pyongyang after the latest test. The White House said with the rocket landing "so close to Russian soil ... the president cannot imagine that Russia is pleased".
China, the isolated North's sole major ally and economic lifeline, has been reluctant to exert pressure to upset the status quo in Pyongyang and risk an influx of refugees from its neighbor.
A North Korean delegation was expected to attend the meeting in the Chinese capital.
