Rapid economic growth in China, India, Brazil and other nations is driving increased global demand for minerals. However, mineral supply is constrained, keeping prices high. This geopolitical context increases risks for countries dependent on foreign mineral imports like the UK. The UK government is taking steps to understand its strategic mineral vulnerabilities and options to improve security of supply through stockpiling, recycling and potentially developing domestic resources. International approaches include bilateral trade agreements, investment in alternative supplies and technologies, and national strategic stockpiles.
