North Korea has previously timed missile launches to coincide with global meetings as a sign of defiance.

China is North Korea's only real ally of substance, although it has signed up to sanctions against Pyongyang following a fourth nuclear test this year, followed by a series of missile tests.

The missile test was also an unwanted distraction for the United States, which has been trying on the sidelines of the summit to finalise a deal with Russian Federation for a ceasefire in Syria.

The official says Obama and Putin met for 90 minutes on Monday at the Group of 20 economic summit in Hangzhou, China.

He said the US aims to focus on its "common enemies" with Russia and encouraged continuing talks between US Secretary of State John Kerry and Russian Foreign Minister Sergey Lavrov.

In Syria on Monday, a string of bombings claimed by the Islamic State terrorist group killed at least 48 people in mostly government-held territory, a day after they lost the last stretch of the Syria-Turkey border under their control.

China produces half the world's annual output of 1.6 billion tonnes of steel and has struggled to decrease its estimated 300 million tonne overcapacity, and rising prices have given companies there an incentive to boost production for export.

"These moves are of pioneering significance in the history of the G20", Xi said about the achievements of the summit which was attended by Prime Minister Narendra Modi, US President Barack Obama and other world leaders.

At her first G20 summit, British prime minister Theresa May held talks about a post-Brexit trade deal with her Australian counterpart Malcolm Turnbull, after a strong warning by Japan that its companies may move to the European Union after the United Kingdom leaves the bloc.

Under the theme of the summit, there are four priorities: "breaking a new path for growth", "more effective and efficient global economic and financial governance", "robust worldwide trade and investment", and "inclusive and interconnected development", Renwick said.

"We need to reignite the engine of growth via innovation", he said, adding that the G20 had adopted "guiding principles" for investment policy management.
