By Rajasik Mukherjee (Reuters) -Shares of Australia's Lynas Rare Earths climbed on Thursday to their highest point in more than two years, after global automakers warned that China's export restrictions on rare-earth materials could lead to production delays.

China has stopped almost all shipments of critical minerals that are needed for cars, robots, wind turbines, jet fighters and other technologies.

A group representing auto suppliers in the United States called on Wednesday for immediate action to address China's restricted exports of rare earths and other minerals, warning the issue could quickly disrupt auto parts production.
