According to Taiwan Trade, the deal will ensure CSC up to 600,000 metric tons (mt) of metallurgical coal supply annually. The move was in line with CSC five year plan, announced last year to boost self-sufficiency in raw materials. CSC may invest up to $2.2 billion worldwide to secure its own supplies of coal and iron ore and reach 30% self-sufficiency. Currently, CSC uses about 30 million mt of coal every year.
