Mintcould not independently verify the full list of Japanese and Indian companies who will be part of discussions. Queries sent to the Japanese and Indian firms remained unanswered till press time. For Indian companies, the need to collaborate with other countries has become important as they struggle to source rare earth magnets from China, which controls 90% of their global supply and imposed restrictions on their exports this April. Alongside, several estimates peg China's global market share in lithium battery production at around 80%, while Japan is estimated to have about 10% share. Experts, though, are sceptical. Srihari Mulgund, partner at consultancy EY-Partheneon, said Indian companies have to look for technology transfer and invest jointly in efforts to localize battery technology. But partnerships with Japanese companies can only offer limited benefits, he argued....
