Chinese regulators have opened investigations into several foreign memory chip makers following a surge in prices that has attracted government concern.

Samsung, the Korean electronics company, said in a statement on Monday that investigators from the State Administration for Market Regulation had visited its Chinese sales offices at the end of last month. The company was "co-operating with Chinese authorities", it said.
