Europe shares open higher, buoyed by Chinese data

Investor sentiment in Asia was buoyed slightly as China's official manufacturing purchasing managers' index (PMI) PMI came in at 50.2, in line with forecasts and slightly higher from April's reading of 50.1. The 50-point mark separates expansion from contraction.

HSBC's final China PMI also showed a slight rise to 49.2 in May from the 49.1 flash reading, a third month of contraction, although hopes of further stimulus sent the Shanghai Composite more than 2 percent higher.

In Europe on Monday, euro zone and U.K. manufacturing PMI is expected at 9:00 and 9:30 GMT, respectively.

Elsewhere, Greece is still a cause for concern for markets. The Greek government and its European creditors agreed on the need to reach a reforms-for-aid deal quickly as Athens missed a self-imposed Sunday deadline for reaching an agreement to unlock more bailout aid, sources close to the talks told Reuters Sunday.

Greece faces a 300 million euro ($329 million) payment to the International Monetary Fund (IMF) Friday and there are doubts the country can honor the debt without further financial aid.
