South Korean steelmaker POSCO and China's Chongqing Iron & Steel Co have signed a memorandum of understanding for a $3.3 billion investment, South Korea's trade ministry said on Friday.

The agreement will cover areas including POSCO's self-developed steel making technology called Finex and mining, the ministry said in a statement. It did not offer other specifics.

POSCO said in September that it agreed to set up a steel mill jointly with Chongqing in Southwest China with an annual production capacity of 3 million tonnes.
