According to an annual report by the Ministry of Natural Resources, the trend has been "increasing" since 1980, reaching the highest levels on record, but it is not occurring uniformly along the coast.
In 2023, the Bohai Sea, Yellow Sea, East China Sea, and South China Sea regions saw significant increases, with the Bohai Sea reaching its highest level since 1980 and the Taiwan Strait having its lowest level in the past eight years.
Coastal provinces and regions, especially Tianjin in the northeast and Hebei in the north, were the most affected, with water levels along their coastlines rising by 145 millimeters and 143 millimeters, respectively.
From 1980 to 2023, the rate of sea-level rise along China's coast was 3.5 millimeters per year, the report said; from 1993 to 2023, the rate increased to 4.0 millimeters per year, exceeding the global average of 3.4 millimeters per year during the same period.
The sustained sea-level rise over the past four decades has had cumulative effects, such as squeezing coastal ecosystems and the loss of wetlands, affecting freshwater resources underground, the ministry said.
In addition, rising sea levels have "intensified natural disasters" such as storm surges and floods in coastal cities.
In 2023, coastal erosion worsened in areas of Liaoning Province in the northeast, Shandong in the east, Jiangsu in the east, and Hainan in the south, with sandy coastlines eroding by an average of 2.7 meters.
Saltwater intrusion also intensified in northern Hebei, southern Shandong, and Jiangsu, with distances exceeding 6.8 kilometers.
Marine disasters in China, characterized by their variety, wide geographical distribution, and high frequency, cause significant economic losses every year, the ministry said.
