Noting that over 90 per cent of rare earth minerals are imported from China, Congress leader Adhir Ranjan Chowdhury on Friday asked the government to give due priority to their exploration in India, saying ”such kind of dependence” on a ”hostile country” will not augur well. Raising the issue in Lok Sabha during Zero Hour, the Congress leader said exploration of rare earth minerals is ”abysmally low” in the country and termed it as ”achilles heels” in India’s strategic planning.
