The Group of 20 major economies will pledge to accelerate their efforts to more effectively collect taxes from multinational digital companies like Google and Facebook, according to a draft of a joint statement by their finance chiefs.

The G20 finance ministers and central bank governors is also set to warn that the world economy continues to face risks from trade conflicts between leading economies, and will call for accommodative monetary policy to ensure the economy recovers.

"We will continue our cooperation for a globally fair, sustainable, and modern international tax system, and welcome international cooperation to advance pro-growth tax policies," reads the draft communique, obtained by Kyodo News ahead of a G20 meeting on Saturday and Sunday in Fukuoka.
