The Group of 20 (G20) leaders remained divided over military action in Syria at the Russian summit on Friday.
US President Barack Obama has been trying to gain support for his plan to launch a strike on President Bashar Hafez al-Assad's government for allegedly using chemical weapons against civilians on August 21st - a claim which Assad denies.
Russia and China, however, warned that any action would be illegal unless sanctioned by a United Nations (UN) Security Council resolution.
US ambassador Samantha Power accused Russia of holding the Security Council hostage by blocking resolutions.
"Even in the wake of the flagrant shattering of the international norm against chemical weapons use, Russia continues to hold the council hostage and shirk its international responsibilities," she told a news conference in New York.
"What we have learned, what the Syrian people have learned, is that the Security Council the world needs to deal with this crisis is not the Security Council we have."
The US and France were the only two nations at the G20 summit to commit to intervention in Syria.
Germany and Italy's failure to support France over military intervention has reportedly infuriated French President François Hollande.
The reluctance of lawmakers to support the move has delayed any possible force until next month after the seven-day opening of general debate at the United Nations General Assembly in New York that starts on September 24th.
G20 highlights pick up in global economy
The G20 said the global economy was recovering but was not out of the firing line yet as emerging markets face rising volatility.
The summit debated on the health of the world economy and addressed concerns about a growth slowdown in developing countries.
The BRICS group of large emerging economies - Brazil, Russia, India, China and South Africa - agreed to put $100bn into a currency reserve pool for any future shocks.
"Facing increased financial volatility, emerging markets agree to take the necessary actions to support growth and maintain stability, including efforts to improve fundamentals, increase resilience to external shocks and strengthen financial systems," Andrei Bokarev, head of the Finance Ministry's international department who was involved in drafting the communique, told Reuters.
The G20's focus on emerging markets gave Europe some breathing space after being in the spotlight of previous summits for its debt crisis.
Europe was rather lauded for its efforts in turning the economy around as recent data pointed to a pick up in the region.
"I want to tell you, at this G20 we were no longer the focus of attention," said European Commission President Jose Manuel Barroso.
"On the contrary, the words we have received were words of sincere appreciation for our efforts, recognising that they are starting to bear fruit."
