Thailand's economic growth rose a 4.3 percent in the first quarter from a year ago and increased 1.2 percent from the previous quarter, according to the National Economic and Social Development Board. Experts said surging exports helped to offset weakness in consumption and investment growth. The board also lowered its 2007 growth forecast range to between 4 percent and 4.5 percent from a previous projection of 4 percent to 5 percent, due to a weakness in the domestic economy caused by political uncertainty.
