China releases a raft of economic data this weekend that include May inflation, export and industrial output figures - all of which could shed light on just how sluggish growth in the world's second biggest economy is proving to be.
Economists said they would pay close attention to the export and inflation numbers in particular.
China's exports grew a stronger-than-expected 14.7 percent in April, although many analysts say that number may have been overstated by companies trying to sneak cash into China to avoid tighter capital restrictions.
A Reuters poll forecasts exports growth in May slowed sharply to 7.3 percent year on year, compared with the strong April numbers.
"We've got two interesting factors when it comes to exports," said Lombard Street Research Economist Freya Beamish. "The first is the extent to which they've [China's authorities] been successful in cracking down on invoicing to get capital in and out of China as we've had questions about whether the trade data are reliable."
The second factor, she said, was to see whether external demand was holding up export growth. "If we now see export growth falling back that's going to be quite serious for the economy," she added.
China's economy slowed unexpectedly in the first quarter of the year, growing an annual 7.7 percent and concerns about the outlook have grown amid signs of weakness. Data on Monday showed that China's factory activity shrank for the first time in May on soft demand for Chinese goods inside and outside the country.
