BEIJING (Reuters) - Profits at China's industrial firms rose 4.3% in the first four months from the same period last year, official data showed on Monday.

The jump followed a 4.3% increase in the first quarter and a slew of divergent activity data for April, according to National Bureau of Statistics (NBS) data.

Industrial profit numbers cover firms with annual revenue of at least 20 million yuan ($2.76 million) from their main operations.
