China's first quarter economic growth slows amid concern about strength of recovery

China's economic growth slowed in the first three months of the year amid concern about the strength of its gradual recovery.

The world's second-biggest economy expanded 7.7 percent in the first quarter from the previous quarter's 7.9 percent

The figures reported Monday fell short of forecasts that growth would rise to at least 8 percent.

China's growth rebounded late last year from its deepest slump since the 2008 global crisis but analysts say a recovery will be weak and still is being supported by government spending.

Some analysts have warned the recovery could be vulnerable if trade or investment weakens.
