G20 countries face calls for action to boost growth

The world's leading economies must do more to boost slowing global growth, the International Monetary Fund and Washington urged as G20 finance ministers gatheredyesterday, with Britain's vote to leave the European Union threatening more disruption.

Central bank chiefs and finance ministers from the world's top 20 economies met in the southwestern Chinese city of Chengdu, and US Treasury Secretary Jacob Lew told journalists it was "a time of continuing uncertainty in the global economic outlook".

"When you look at the political developments around the world, most recently the referendum in the United Kingdom, it really reinforces the importance of concentrating on shared growth," he said.

Britain's new finance minister Philip Hammond yesterday met his German counterpart Wolfgang Schaeuble for the first time, and held talks with Chinese central bank chief Zhou Xiaochuan.

"In Chengdu for G20 -- will be reassuring world that Britain is open for business & will continue to be a competitive open trading nation," he tweeted.

According to a draft communique the G20 will seek to stress the impact of Brexit can be tackled, Bloomberg News reported.

"Members of the G20 are well positioned to proactively address the potential economic and financial consequences stemming from the UK referendum," it quoted the draft document as saying.

Just ahead of the meeting, the IMF called on key G20 nations to boost government spending.

"Global growth remains weak, and downside risks have become more salient," the Washington-based lender said in a report. "Growth could be even lower if the current increases in economic and political uncertainty in the wake of the 'Brexit' vote continue."
