SINGAPORE, Nov 13 (Reuters) - The problems facing the international financial system have not been fully addressed and any moves toward protectionism will not help, Chinese President Hu Jintao said at a forum of Asia Pacific business and political leaders in Singapore on Friday.

Hu said China's stimulus focus was on expanding domestic demand.

China's economy has picked up over the course of the year, fuelled by government stimulus spending, with the annual GDP growth rate accelerating to 8.9 percent in the third quarter from 7.9 percent in the second and 6.1 percent in the first, virtually assuring China of reaching its 8 percent full-year growth target.
