China's Oct. manufacturing index hits highest level since April 2012

China's manufacturing activity reached the highest level in October since April 2012, supported by government stimulus measures focusing on infrastructure, official data showed Friday.

China's official manufacturing Purchasing Managers' Index rose to 51.4 from 51.1 in September, according to the National Bureau of Statistics and the China Federation of Logistics and Purchasing.

The index, which posted a better-than-expected rise for the fourth straight month, is at the highest level since 53.3 in April 2012.

PMI readings above 50.0 signal an improvement in business conditions, while readings below 50.0 signal deterioration.

In another sign of recovery in the world's second-largest economy, the October sub-index measuring manufacturing production rose to 54.4, also the fourth straight monthly increase, but the export sub-index fell to 50.4 from 50.7 in September.
