China's GDP grew at a slightly faster-than-expected pace in the second quarter, according to official data published Monday, as surging industrial production and solid exports kept the world's second-largest economy humming in the face of significant concerns for its financial sector.

China's economy expanded at an annual 6.9% clip in the three months ending in June, the National Statistics Bureau (NSB) said, a rate that was modestly faster than the 6.8% pace anticipated by analysts but largely in line with the rate of growth over the first quarter. Industrial output, which rose 7.6% from the same period last year, paced the GDP gains, while an 11% surge in retail sales underscored the strength of the domestic consumer economy.
