The finance ministers of the G20 group of nations are meeting in Moscow amid concerns over so-called currency wars between the major trading powers.
The finance ministers of the G20 group of nations are meeting in Moscow amid concerns that major trading powers may be heading towards a currency war.
Japan has moved to force down the value of the yen, and France is concerned about the strength of the euro.
Japan's monetary stance has seen a big decline in the yen, while the euro has risen against a basket of currencies.
Reports suggest that the G20 will back previous statements warning not to interfere with the market rates of their currencies.
The value of a country's currency has a big impact on its trade and there are fears nations may try to influence markets to help boost their economies.
Recently, the G7 rich nations said they would "not target exchange rates".
The G20 has previously asked nations to refrain from currency devaluation.
But the G7 also said: "We are agreed that excessive volatility and disorderly movements in exchange rates can have adverse implications for economic and financial stability."
Earlier this week, the G7 group of nations issued a statement saying they would "not target exchange rates".
That confused markets as to whether the G7 was really sending a message to Japan for forcing down its currency.
Countries attempt to devalue their weaker currencies in order to make their exports cheaper.
"The language may differ (from the G7), but the intent will remain the same," the minister was quoted as saying by the Reuters news agency.
The talks will begin on Friday.
The euro has risen by 6% against a basket of other currencies in the past six months.
At a meeting of euro ministers, French Finance Minister Pierre Moscovici said he was worried that the rising single currency is making the country's goods less competitive.
And the European Central Bank president Mario Draghi was deemed to be trying to talk down the euro at his press conference following the bank's latest rate decision.
