TOKYO (AP) — Japan's exports in February grew 1.8 percent compared to the same month a year ago, according to Ministry of Finance data released Monday.

Worries are growing about a possible trade war over President Donald Trump's 25 percent tariffs on steel and 10 percent on aluminum.

Japan is asking for an exemption.

Exports are expected to grow in coming months, boosted by global economic growth. Japan exports much of its steel to Asia and not the U.S.

Exports grew to 6.46 trillion yen ($61 billion). Japan's imports in February grew 16.5 percent on year also to 6.46 trillion yen ($61 billion), when rounded off, leaving a surplus of 3.4 billion yen ($32 million), the ministry said.

By country, Japan's exports to the U.S. in February grew 4.3 percent.
