Malcolm Turnbull has arrived in Hamburg for a G20 summit deeply divided over how to tackle North Korea's ambitions and threatening to fracture over global trade.
The prime minister's first meeting will be with host leader, German Chancellor Angela Merkel, which will focus on trade, innovation, energy and global security.
Germany shares Australia's interest in calling on China to do more to tackle North Korea's blatant breaches of UN Security Council resolutions banning missile testing.
Mr Turnbull has arrived amid a security lockdown in the German port city, with tens of thousands of protesters rallying on the streets to shut down the summit.
It will be the first G20 for US President Donald Trump, who said in a speech in Poland ahead of the summit his country would do all it could to end extremism, including closing its borders.
