Qingdao Port, China's second largest foreign trade port, saw its foreign trade cargo throughput up 21 percent year on year in the first six months of 2010, the port's chairman said Thursday.

Foreign trade cargo throughput hit 128.87 million tonnes in the first half of the year, said Chang Dechuan, chairman and president of Qingdao Port.

Total throughput at the port, both domestic and foreign trade, totaled 170.48 million tonnes, up 8.7 percent year on year.

Chang attributed the increased cargo throughput to a series of technological innovations and a low-carbon drive.

He gave no details concerning revenues.
