Analysts expect China's fourth quarter and 2012 growth figures due Friday to show the world's No. 2 economy continuing to bounce back from its worst slump since the 2008 financial crisis.
Sentiment improved last week after Japan announced a $224 billion stimulus package to boost its recession- and deflation-mired economy. A strong economic recovery has eluded Japan for more than 20 years since the bursting of its financial bubble in the early 1990s.
China, meanwhile, reported improving exports and imports last week, a sign of higher demand both inside and outside the country. Analysts expect to see more signs of improvement when China releases a slew of data on Friday, including factory output, investment and retail sales.
"We are on the optimistic side of the market," Dariusz Kowalczyk of Credit Agricole CIB in Hong Kong said in an email commentary. "Such an outcome would put to rest any remaining doubt about China escaping a hard landing and sailing smoothly through the troubled global waters."
