Scott Morrison warns of 'collateral damage' in region from US-China rift

PM to call for China to match its economic power with 'additional responsibilities' in major speech before G20 summit in Tokyo

The prime minister, Scott Morrison, has warned that the "strained" relationship between the US and China risks "collateral" damage in the region, amid growing uncertainty in the global economy.

In a major speech ahead of the G20 summit in Osaka this weekend where the US president, Donald Trump, will meet with China's president, Xi Jinping, Morrison has called on China to match its extraordinary economic power with "additional responsibilities", saying it has been a key beneficiary from the rules-based international trading system.
