Because of international social and economic sanctions, it is only this help that has caused North Korea's large material needs. However, for reciprocal trade, North Korea has to increase exports of mineral products in exchange for a large amount of foreign exchange. According to the latest research released by the Korean Enterprise Bank Economic Research Institute and the Yonhap News Agency on the 6th, North Korea ’s exports of minerals to China in the first three quarters of this year amounted to US $ 850 million, an increase of 2.5 times over the same period last year. According to the study, the price of North Korean exports of minerals to China is lower than the price in the international market. This move is to raise foreign exchange needed for "Daqing" next year.

 

In addition, due to the tightness of North Korea's national defense, in addition to the purchase of Soviet fighter jets, it is more expensive to buy this fighter jet. Some experts have disclosed that of the 700 existing air defense fighters in North Korea, about 500 were imported from China. If we do not increase the export of mineral products, then in the future, if we want to buy more advanced J-20s from China, there will be a lot of funding shortages.

 

It is reported that the study analyzed the "Import and Export Trend of Mineral Resources between China and the DPRK" (2008-2011) released by the Chinese government and found that China imported 8.423 million tons of mineral resources from North Korea in the first nine months of this year, with a total value of 852 million The US dollar increased by 1.7 times and 2.5 times respectively from the 3.048 million tons and 245 million US dollars in the same period last year. Most of the minerals imported from China are anthracite. The price of anthracite is US $ 101 per ton, which is lower than the price of US $ 200 for high-quality anthracite in the international market. However, reports say that North Korea has ordered a ban on coal exports as winter approaches to its own coal tensions. But I do not know what the North Korean side will rely on to obtain foreign exchange.
