The International Monetary Fund forecast Monday that Japan's economy will grow 1.1 percent this year, up 0.1 percentage point from its estimate in July due to the uptick in growth and domestic demand in the April-June quarter.

But in its latest World Economic Outlook, the IMF cut its global economic growth forecasts for 2018 and 2019, saying trade policy tensions and the imposition of import tariffs are taking a toll on commerce while emerging markets struggle with tighter financial conditions and capital outflows.

The IMF said it was now predicting 3.7 percent global growth in both 2018 and 2019, down from its July forecast of 3.9 percent growth for both years.
