Donald Trump, world leaders head to G20 summit under North Korea shadow.

US President Donald Trump meets other world leaders at Germany’s G20 summit from Friday, with North Korea’s first successful test of an intercontinental ballistic missile casting a long shadow over the gathering at the heavily-fortified venue.

The rising global threat posed by Pyongyang is likely to see conflicts over climate and trade take a back seat as regional neighbours China, Japan and South Korea gather with Trump and Russian strongman Vladimir Putin in Hamburg.
