According to customs statistics and related investigations, after 2010, China's imports of nickel ore from Indonesia have always accounted for more than 70% of Indonesia's total nickel ore exports, while the proportion of nickel ore imported from the Philippines accounted for more than 90% of its total exports. According to data released by the General Administration of Customs of the People’s Republic of China, China imported 56.129 million tons of nickel ore and its concentrate (physical volume) in 2019, of which 23.904 million tons were imported from Indonesia and 29.937 million tons were imported from the Philippines. The total amount of nickel ore and concentrate imported by China accounted for 95.9% of China's total imports of this resource.

From the perspective of imported ferronickel, China imported a total of 1,497,700 tons of ferronickel in 2019, of which imports from Indonesia were 1,357,700 tons, accounting for 69.6% of the country alone.
