Oil giant 'in business'

The main supplier of jet fuel to China is continuing to do business despite a criminal investigation of its €442.6m losses on derivative trading, the company said.

The Singapore Exchange and central bank said Singapore-listed China Aviation Oil (Singapore) Corporation was under investigation by the Commercial Affairs Department, which investigates white-collar crime.

The scandal is the latest of several to hit the Chinese corporate world as companies with little experience in foreign markets expand their presence abroad.
