Japan's economy will grow 1 percent next year before slowing to a 0.8 percent expansion in 2018, the Organization for Economic Co-operation and Development said in its latest global economic outlook.

A rebound in international trade will help drive Japan's export growth higher over the next two years, supporting business investment as fiscal stimulus fades, the Paris-based OECD said Monday. It sees Japan's gross domestic product increasing 0.8 percent this year.

"With stronger exports, and the capacity shortages and high profits, we expect that business investment will also get stronger in the next few years," Randall Jones, head of the OECD's Japan-Korea desk, said during a briefing.
