Apple has been fined NT$20 million (US$663,332) by the Taiwan Fair Trade Commission for interfering with the pricing of the iPhone by three mobile carriers, according to reports.The antitrust agency found Apple's unit in charge of Taiwan sales violated article 18 of the Taiwan's Fair Trade Act by asking operators Chunghwa Telecom, Far Eastone Telecommunications and Taiwan Mobile to submit pricing plans for approval by Apple, which had also recommended changes in the prices.Apple's agreements with the operators are said to have stipulated, for example, that subsidies these companies offer for buying iPhones with contracts cannot be lower than those of their competitors.The Fair Trade Commission had not issued a statement on the order on its English website, though a Chinese version was available.Article 18 of the Fair Trade Act
