Shenzhen Port — a collective name for several ports along the city’s 260-kilometer coastline — had handled 30.1 million twenty-foot equivalent units (TEUs) of containers as of Oct. 17, surpassing the 30-million mark three weeks earlier than last year, the city’s transport bureau said. The port operates more than 270 international container routes. This year, it established sister-port ties with Greece’s Port of Piraeus and South Korea’s Port of Yeosu-Gwangyang, bringing its total to 31. Cargo volume between Shenzhen Port and APEC member economies accounted for over half of the city’s foreign trade and APEC economies are the port’s largest export market
