Samsung and Apple may be investigated by South Korean anti-trust authorities, a report claims.

If it happens, the investigation will focus on the deal reached between the two companies under which Samsung reportedly sold Apple the flash memory it needs for some iPods at, "below market prices", a local report has claimed.

In a radio talk show, South Korea Fair Trade Commission (FTC) chairman Kang Chul-kyu said: "Questions about Samsung and Apple engaging in unfair trading could be investigated by the antitrust body", the report claims.

This follows complaints from Korean companies who accused Samsung of favouring Apple over and above the needs of local industry. Samsung is said to have sold 40 per cent of its flash memory production to Apple at a discount rate.

However, Samsung CEO Hwang Chang-kyu has claimed: "There was nothing unfair about the businesses with Apple."
