China's iron ore oil dependence on foreign countries exceeds 56%
The 2011 China Land and Resources Bulletin released recently shows that China's foreign mineral products are currently at a high level of dependence. Among them, the dependence on petroleum and iron ore is more than 56%. The communique said that in 2011, the output of China's major mineral products maintained a general growth trend, and the supply capacity was improved, but the gap between supply and demand of bulk mineral products remained large. In 2011, the total import and export volume of foreign mineral products of the country was 957.1 billion US dollars, a year-on-year increase of 34.3%. Among them, the import value increased by 34.5% year-on-year; the export value increased by 33.9%. Imports of crude oil, coal, iron ore, bauxite, manganese ore, chromite, nickel ore and other mineral products increased by different degrees from the previous year. In particular, after the net import in 2009, the import volume in 2011 reached 222.28 million tons, an increase of 20.3% over the previous year. Among them, the external dependence of oil is 56.7%, and the external dependence of iron ore is 56.4%. The bulletin pointed out that in 2011, geological prospecting work rose to the national strategy, and the investment in geological mineral exploration continued to grow. The total investment for the year was 109.23 billion yuan, up 6.7% year-on-year; among them, oil and gas mineral investment increased by 6.9%, and non-oil and mineral investment increased by 6.4. %. Most major minerals have identified resource reserves to keep growing. Among them, energy and mineral resources have found that resource reserves have generally increased.
