Shenzhen Port, one of China's busiest ports, saw its container throughput in 2010 hit a record high of 22.51 million TEUs, 23.34 percent more than in 2009, according to the Transport Commission of Shenzhen Municipality.



The 770,000 TEUs increase was the highest on record and reflected the eighth consecutive year that the port has maintained its position as the world's fourth busiest port, reported China Knowledge Press.



In 2010, about 24,353 international container lines operated at the port, and its overseas container throughput accounted for 75 percent of the total.
