The Organization for Economic Cooperation and Development on Tuesday raised its forecasts for the global economy for 2018 and 2019, factoring in the impact of tax cuts and spending in the United States.

Robust exports to Asia and the effect of a supplementary budget for fiscal 2017 through March will help support Japan's economic growth, the OECD said as it lifted its forecasts for the world's third biggest economy also for both years.

"The world economy will continue to strengthen over the next two years," the OECD said. "Stronger investment, the rebound in global trade and higher employment are helping to make the recovery increasingly broad-based."
