Ningbo Zhoushan port, China's busiest port, saw cargo throughput rise 5.5 percent year on year to 557.96 million tonnes in the first half of 2019.

Meanwhile, the container throughput at the port in eastern China's Zhejiang Province reached 13.91 million standard containers in the January-June period, up 4.7 percent year on year, according to statistics from the Ministry of Transport. The container throughput ranked second in the country only after the Shanghai port.

The Ningbo Zhoushan Port Group, the operator of the port, said the port has been accelerating smart port construction to improve efficiency and tapping the inland market to boost business this year when facing unstable economic and trade conditions.

The port has embraced the Belt and Road Initiative by optimizing shipping routes to related regions. The Belt and Road regions contributed to over 40 percent of its container throughput, with the container throughput from Southeast Asia and the Mediterranean routes in the first half rising 41 percent and 15.8 percent, respectively.

In 2018, the port reported an annual cargo throughput of over one billion tonnes for a second straight year, being the only one in the world to exceed the one-billion-tonne level. Its annual container throughput exceeded 26 million standard containers, ranking among the top three ports in the world.
