China's economy expanded 7.4 percent year-on-year in January-March, China's National Bureau of Statistics (NBS) said Monday, weaker than the 7.7 percent expansion in October-December.

While the figure exceeded the median forecast of 7.3 percent in a survey of 13 economists by AFP, it is the latest in a string of figures showing the world's number two economy and key driver of global growth is slowing.

"The GDP data is better than expected but it's lower than the last quarter and I suspect investors will still have the 'China is slowing down' story on their minds," David Lennox, resource analyst at Fat Prophets in Sydney, told AFP. "Oil prices will likely remain under pressure as a result," he said.

Dealers are also awaiting the latest US stockpiles report out later Wednesday for clues about demand in the world's biggest economy.
