China and Germany, the world%u2019s second-largest and fourth-largest economies respectively, expressed concern about Federal Reserve plans to pump $600 billion into the U.S. economy.
The Fed announced plans to buy $600 billion of assets earlier this week. The Fed hopes that the move, known as quantitative easing, will help boost the U.S. economy and lower unemployment.
The U.S. trade deficit unexpectedly increased in May to $42.3 billion, from a revised figure of $40.3 billion in April.
Imports outpaced exports in May, driven by increased demand for consumer goods and cars, the Commerce Department said.
