Security Of China’S Strategic And Critical Minerals Under Background Of Great Power Competition, Anjian Wang, Xiaojing Yuan
Security Of China’S Strategic And Critical Minerals Under Background Of Great Power Competition, Anjian Wang, Xiaojing Yuan
Bulletin of Chinese Academy of Sciences (Chinese Version)
Strategic and critical minerals are a type of resource that is essential to the country's economic development, indispensable to strategic emerging industries, and closely related to geopolitics. The types of strategic and critical minerals show some laws of spatial-temporal evolution due to the different stages of national economic development, economic structure and global industrial division of labor. Especially since the new century, with the rapid development of strategic emerging industries such as information technology, artificial intelligence and renewable energy, the connotation of strategic critical minerals has been continuously extended and closely connected with the industrial chain, highlighting its important position …
Analysis Of Critical Mineral Strategies Of Us And Eu And Their Enlightenment To China
Analysis Of Critical Mineral Strategies Of Us And Eu And Their Enlightenment To China
Bulletin of Chinese Academy of Sciences (Chinese Version)
As the world's major consumers of critical minerals and China's primary competitors, US and the EU have developed comprehensive and systematic critical mineral strategies, which have significant impact on China's resource security. To assist in developing China's critical mineral strategy, by thoroughly examining the critical mineral strategies of US and EU, this study finds their strategic attempts to slow China's development, summarizes their characteristics in the preparation, implementation mechanism, and main strategic measures, and, based on this, proposes suggestions for raising the safety level of China's critical minerals.
Recycling Of Critical Metals In Green And Low-Carbon Transition: Strategies And Countermeasures, Gang Liu, Litao Liu, Xin Ouyang, Qiance Liu, Xiang Li, Qiang Yan
Recycling Of Critical Metals In Green And Low-Carbon Transition: Strategies And Countermeasures, Gang Liu, Litao Liu, Xin Ouyang, Qiance Liu, Xiang Li, Qiang Yan
Bulletin of Chinese Academy of Sciences (Chinese Version)
As green and low-carbon transition has gained world-wide recognition and become the inherent requirement of fully building a modern socialist China, the consumption of critical metals will increase drastically in the next decades. Meanwhile, this will mean a continually increasing potential of critical metals recycling. Facing changes and pandemic unseen in a century and increasing geopolitical conflicts, it has become a strategic consensus on the national security level for Western countries like the United States and Europe Union to acknowledge and enhance the role of recycling in secure provision of critical metals. Here, in this study, we have discussed the …
Challenges And Security Strategies Of China’S Critical Metals Supply For Carbon Neutrality Pledge, Weiqiang Chen, Peng Wang, Weiqiong Zhong
Challenges And Security Strategies Of China’S Critical Metals Supply For Carbon Neutrality Pledge, Weiqiang Chen, Peng Wang, Weiqiong Zhong
Bulletin of Chinese Academy of Sciences (Chinese Version)
The grand transition to low-carbon energy system is essential to bend the growing carbon emission and further achieve the dual carbon goals. Critical metals such as rare earth elements, lithium, cobalt, nickel, and platinum are widely considered as the material base to support low-carbon technologies. However, given the supply of those metals are scarce and risky, the emerging conflicts between their supply and demand have spurred global attention and competition among countries. This study aims to explore the linkage between critical metals and low-carbon energy systems with a particular focus on the bottlenecks of China's supply chains of those critical …
China’S Rare Earth Supply And Demand Pattern And Balanced Utilization Strategy From Perspective Of Elements, Tao Dai, Tianming Gao, Bojie Wen
China’S Rare Earth Supply And Demand Pattern And Balanced Utilization Strategy From Perspective Of Elements, Tao Dai, Tianming Gao, Bojie Wen
Bulletin of Chinese Academy of Sciences (Chinese Version)
Rare earth is one of the key minerals in the global competition. At present, the global rare earth resources and supply pattern are changing, and Western countries are actively building a supply chain to replace China. This paper describes the evolution of China's rare earth supply and demand pattern from the perspective of elements, analyzes the dislocation of supply and demand of China's rare earth elements and the challenges it faces under the great changes, and puts forward the balanced utilization strategy of rare earth elements, which provides an optimization plan for promoting the globalization of the industrial chain and …

Inverting Passive Margin Stratigraphy For Marine Sediment Transport Dynamics Over Geologic Time, Charles Shobe, Jean Braun, Xiaoping Yuan, Benjamin Campforts, Boris Gailleton, Guillaume Baby, François Guillocheau, Cécile Robin
Inverting Passive Margin Stratigraphy For Marine Sediment Transport Dynamics Over Geologic Time, Charles Shobe, Jean Braun, Xiaoping Yuan, Benjamin Campforts, Boris Gailleton, Guillaume Baby, François Guillocheau, Cécile Robin

Passive margin stratigraphy contains time-integrated records of landscapes that have long since vanished. Quantitatively reading the stratigraphic record using coupled landscape evolution and stratigraphic forward models (SFMs) is a promising approach to extracting information about landscape history. However, there is no consensus about the optimal form of simple SFMs because there has been a lack of direct tests against observed stratigraphy in well-constrained test cases. Specifically, the extent to which SFM behaviour over geologic space and timescales should be governed by local (downslope sediment flux depends only on local slope) versus nonlocal (sediment flux depends on factors other than local …
