Harper arrived Wednesday in Seoul, where he is expected to push for bold, co-ordinated economic action by the G20 world leaders. After the summit, the prime minister will travel to Yokohama, Japan, for this year's forum for Asia-Pacific Economic Co-operation.

"It's going to be all economics all the time, two summits in a row," the CBC's Terry Milewski reported from Seoul on Wednesday.

Harper has warned his G20 counterparts ahead of the summit not to let the struggling recovery distract them from cutting budget deficits and trade imbalances.

In a letter to the G20 leaders last week, Harper reminded them of promises made during the June summit in Toronto to cut deficits and debt and subsequent agreements on guidelines for their current accounts.

Ahead of opening talks at the summit, the prime minister will also join his Australian and British counterparts, Julia Gillard and David Cameron, for a joint Remembrance Day ceremony.  

Fears over 'currency war'

The aim of the G20 meeting is to boost employment, spur economic growth and avoid a harmful currency war. Leaders are poised to agree in principle to make sure their trade, investment and fiscal balances don't go too much into the red or the black.

But several emerging market countries are suspicious of recent U.S. Federal Reserve moves to pump $600 billion into a bond-buying program — essentially creating money.

They say the so-called quantitative-easing could trigger a round of competitive exchange-rate devaluation, or a currency war.

There is growing anger over the U.S. decision. Russia has said that the U.S. needs to consult with all key players in the world economy before taking such action, while German Finance Minister Wolfgang Schaeuble called American economic policy "clueless."

China and Brazil have also been critical. But Canada has been quietly supportive, with officials saying that the drastic measures being taken in the U.S. show how dire the situation is.
