    Indonesia has rapidly ascended to the position of the world’s second-largest cobalt producer, leading to a substantial decline in the price of this essential battery metal and intensifying Western concerns over China’s stronghold in the electric vehicle supply chain. Last year, the Southeast Asian nation produced 9,500 tonnes of cobalt, representing 5 percent of the global supply, a significant leap from its negligible production levels before 2021. Nevertheless, Indonesia still trails significantly behind the Democratic Republic of Congo, the top global supplier, which commands a dominant 73 percent share of the market.
