NEW YORK, Sept 17 (Reuters) - Any proper approach to free trade should focus not just on lowering barriers to trade but also on having flexible exchange rates, Canadian Prime Minister Stephen Harper said on Thursday.
Without naming China, which has resisted floating currency rates, he said a flexible regime was the only way to prevent unsustainable imbalances from growing in the economy.
He also voiced concern about legislation in the U.S. Congress envisaging tariffs on high-carbon energy imports, saying this could lead to protectionism which could jeopardize economic recovery. (Reporting by Randall Palmer, Editing by Chizu Nomiyama)
