MANILA - The Asian Development Bank (ADB) on Tuesday upgraded its growth forecasts for the Philippines, citing strong domestic demand.

Gross Domestic Product is expected to grow 6.4 percent this year, higher than the previous forecast of 6 percent. Next year's growth forecast was raised to 6.2 percent, the Manila-based bank said in a statement.

Growth is expected to moderate in the second half in the absence of election spending, which drove GDP growth in the first six months of the year to 6.9 percent.

The ADB said President Rodrigo Duterte's 10-point economic roadmap was expected to sustain the country's robust growth.
