The sea areas, especially the major ports in South China, have already turned red lights on imported coal. In the first quarter of this year, the major reasons for the large year-on-year increase in purchases of imported coal by coastal provinces. In March, China imported 26.7 million tons of coal, a year-on-year increase of 4.61 million tons, an increase of 20.87%, and an increase of 5.794 million tons, an increase of 27.71%. From January to March this year, China's cumulative import of coal was 75.413 million tons, an increase of 10.712 million tons, an increase of 16.56%. In order to achieve the goal of controlling the total amount of imported coal that was issued by the government at the beginning of the year, it is expected that the tightening of imported coal will continue for a long period of time when the coal price continues to be in a relatively reasonable range. In the short term, the import coal restriction policy will have less impact on imported coal prices. In the medium and long term, this policy favors domestic coal prices, which is bad for imported coal prices.
