"The strong dollar is hurting exporters as well as hitting domestic sales as firms compete against inflows of cheap imports. Low oil prices are meanwhile hitting demand for goods and machinery from the energy sector. There are signs that consumers are becoming more cautious in relation to spending as interest rates lift off their historic lows, and overseas demand remains in the doldrums. All of these factors look set to continue to hurt manufacturers, and even intensify, in coming months," Markit's Chief Economist Chris Williamson said.

The Chinese Markit/Caixin manufacturing PMI declined to 48.2 in December from 48.6 in November, missing expectations for a reading of 49.0.

Production fell in December, partly driven by a further drop in total new work. Companies continued to shed their staff.

"The Caixin China General Manufacturing PMI for December is 48.2, down 0.4 points from the reading for November. This shows that the forces driving an economic recovery have encountered obstacles and the economy is facing a greater risk of weakening. More fluctuations in global markets are expected now that the U.S. Federal Reserve has started raising interest rates," Dr. He Fan, Chief Economist at Caixin Insight Group, said.

Both Saudi Arabia and Iran are major oil producers and these tensions raise concerns over stability of supplies, however the persistent global supply glut and recent weak economic data from China (world's second-biggest consumer of oil) limit bullish expectations.
