China’s third-quarter GDP grew 4.9% as compared to a year ago, according to data released Monday by the country’s National Bureau of Statistics.

Meanwhile, retail sales in China rose 3.3% in September from a year earlier.

OCBC Bank’s Vasu Menon described the Chinese retail sales print as a “big surprise.”

“The headline numbers seem like they’ve missed the mark but when you drill down to the details, especially domestic consumption, I think that offers some room for optimism,” Menon, executive director of investment strategy, wealth management Singapore at the firm, told CNBC’s “Street Signs Asia” on Monday.

“Bear in mind that 4.9% growth is still a decent number — especially given the current environment — and is a pick up from the previous quarter which was 3.2%,” he said.
