Finance Minister Bill Morneau says Canada to 'remain resolute' in coalition to destroy ISIS

Canada will "remain resolute" in its fight against ISIS, Finance Minister Bill Morneau said Sunday at a G20 leaders summit in Turkey.

"We have committed to bringing back the CF-18s," Morneau said, referring to Justin Trudeau's pledge to return to Canada the fighter jets conducting anti-ISIS combat missions abroad. "But in the broader context we remain absolutely committed to the coalition." 

Morneau's comments come on the heels of U.S. President Barack Obama's vow to step up efforts to eliminate the Islamic State group in Syria and prevent it from carrying out attacks like those in Paris, and European leaders' urging of Russia to focus its military efforts on the radical Islamists.

Obama described the killings in Paris claimed by ISIS as an "attack on the civilized world" and said the United States would work with France to hunt down those responsible.

The two-day summit brings world leaders just 500 kilometres from Syria, where a 4½-year conflict has transformed ISIS into a global security threat and spawned Europe's largest migration flows since the Second World War.

"Traditionally the G20 has been a forum primarily to discuss economic issues facing the globe ... (but) the sky has been darkened by the horrific attacks that took place in Paris just a day and a half ago," Obama said in a statement after meeting Turkish President Tayyip Erdogan.

"The United States and its allies will redouble efforts to find a peaceful solution in Syria and prevent Islamic State militants from perpetrating attacks like those in Paris."

Obama and his Western allies now face the question of how the West should respond after Islamic State again demonstrated it posed a threat far beyond its strongholds in Syria and Iraq.

"We remain committed to the coalition," Morneau said. "We believe we do need to be part of the fight to degrade and destroy ISIL. We only question the way that we should best do that."

Washington already expects France to retaliate by taking on a larger role in the U.S.-led coalition's bombing campaign against Islamic State.

But European Council President Donald Tusk said Russia too should focus its military operations on Islamic State, rather than on the Syrian opposition battling President Bashar al-Assad, urging cooperation between Washington and Moscow.

"It should be our common aim to coordinate our actions against Daesh (IS) and for sure the cooperation between the United States and Russia is a crucial one," he said.

Russia joined the conflict a month and a half ago with air strikes in Syria, but has been targeting mainly areas controlled by the moderate Syrian opposition fighting Assad, its ally, rather than Islamic State, its critics say.

Turkey and Western allies, by contrast, want Assad out.

UN Secretary-General Ban Ki-moon said he welcomed the renewed sense of urgency to find a solution to the war in Syria after the Paris attacks, adding the world had a "rare moment" of diplomatic opportunity to end the violence.

Obama and Russian President Vladimir Putin have no formal bilateral meeting planned. As the leaders moved into place for a group photo on Sunday, Putin approached Obama and they shook hands, exchanging words for only a few brief moments.

Obama is also seeking to coax other European and Middle Eastern countries into more tangible steps to show their military commitment and will hold a bilateral meeting with Saudi Arabia's King Salman, U.S. officials said. In a call late last month, the two leaders affirmed the need to cooperate in fighting Islamic State.

Obama said he had also discussed in his meeting with Erdogan the progress made by foreign ministers in Vienna, who on Saturday outlined a plan for a political process in Syria leading to elections within two years, although differences over Assad's fate still remained.

On the economy, G20 leaders pledged to use all policy tools to address uneven economic growth that falls short of expectations, according to a draft communique seen by Reuters on Sunday.

According to a separate statement due to be released later on Sunday, a draft of which was also seen by Reuters, they also agreed to step up border controls and aviation security in the wake of the Paris attacks, which they condemned as "heinous."
