Shanghai Port, whose container throughput totalled 36.5 million TEUs in 2015, reported a preliminary net profit of 6.5 billion yuan ($989.35 million) in 2015, down from 6.8 billion yuan a year earlier, it said in an exchange filing on Monday.
The port is expected to post its final annual results with outlook comments in March. The last time it logged a profit fall was in 2011, when net profit was down 12.8 percent, according company data posted on Eikon.
China, the world's second largest economy, will face great difficulty in achieving economic growth above 6.5 percent over the 2016-2020 period due to slowing global demand and rising labor costs at home, the China Securities Journal quoted top state adviser Li Wei as saying on Monday.
In 2010, Shanghai port overtook the Port of Singapore to become the world's busiest container port. Shanghai's port handled 29.05 million TEUs, whereas Singapore's was a half million TEUs behind.
The Port of Shanghai faces the East China Sea to the east, and Hangzhou Bay to the south. It includes the confluences of the Yangtze River, Huangpu River and Qiantang River.
