Prime Minister Malcolm Turnbull has joined with leaders of the US, China and Russia in urging governments to do more in combating terrorism.
The 21 leaders of the Asia-Pacific Economic Cooperation on Thursday issued a statement in which they strongly condemned recent attacks in Paris, Beirut and against the Russian aircraft over the Sinai.
In a declaration at the end of the Manila meeting, they stressed solidarity amongst governments to work together in the "urgent" fight against terrorism. But they also highlighted how trade and stronger economies could prevent citizens from taking up arms in the first place.
"Economic growth, prosperity, and opportunity are among the most powerful tools to address the root causes of terrorism and radicalisation," their statement said.
Terror attacks have overshadowed the usually trade-heavy summit this year with leaders using talks on the sidelines to renew the fight against Islamic State extremists in Syria and Iraq.

Mr Turnbull and US President Barack Obama used their first formal meeting at APEC to vow to ramp up pressure against IS, both arguing a political solution in Syria was the most effective way to defeat them in the long-term.
But while the prime minister favours a power-sharing deal in the war-ravaged country, he insists IS would not form part of that.
"The so-called Islamic State seeks to establish its own caliphate - it has no interest in any political settlement," he told reporters in Manila on Thursday.
APEC leaders also vowed to work together and share knowledge on ways to secure infrastructure, financial systems and trade routes from terrorist activities.
