In the dairy case, six foreign suppliers were fined for vertical price-fixing, or setting minimum retail prices for baby formula. Such a tactic is common in foreign markets but lawyers say the anti-monopoly law prohibits it.
A spokesman for the Cabinet's planning agency was quoted by Chinese media on Aug. 16 as saying it would look into possible anti-monopoly violations in petroleum, telecommunications, autos and banking.
Drug manufacturers have been rattled by investigations into whether Britain-based GlaxoSmithKline PLC and French rival Sanofi SA bribed doctors to prescribe their medications.
Investigations have targeted only foreign companies, including those with the strongest standard operating procedures, or SOPs, to prevent employee misconduct, said the president of the chamber's pharmaceutical working group, Bruno Gensberger.
"What I feel a little bit unfair, the foreign companies that are most serious about SOPs have been the most investigated and the most discriminated," said Gensberger. "To my knowledge, today no Chinese company has been investigated."
Authorities say they are investigating whether employees of GSK and Sanofi improperly paid doctors, hospital administrators and others to encourage use of its medications. GSK employees are accused of laundering money through travel agencies to evade its internal anti-bribery controls.
Such payments are widespread in China's medical system. Health experts say such bribery by Chinese drug companies is routine, while global suppliers are less likely to engage in it due to anti-corruption laws in their home countries.
