There is little difference, but it is higher than international conferences. The reason is that China has a large demand for coal and a high output, and the international market just follows the pricing. In 2008, China imported 40.4 million tons of coal, which is insignificant compared with the domestic total demand of 2.8 billion tons of coal. At present, the coal trade volume in the international market is less than 900 million tons, and the demand variables of tens of millions of tons will lead to price fluctuations. Therefore, the international market price is often influenced by the coal price in China. Finally, the coal price in the international market is often only slightly lower than the domestic coal price after freight, but there is not much difference.
