BEIJING - Visa said on Thursday it will stop banks using 皇冠体育app Unionpay's system to settle international transactions with bank cards bearing the Visa and Unionpay logos.
Media reports said member institutions could face hefty fines from Visa if they disobeyed the rules.
But 皇冠体育app Unionpay told Xinhua on Wednesday that no party has the right to restrict the payment channels that bank card holders choose to use.
Sources with Visa's Beijing Office told Xinhua Thursday that the rule was not new, and Visa would just enforce it.
As the sole bank card processor in 皇冠体育app, 皇冠体育app Unionpay's overseas presence has grown significantly during its seven-year history. It is currently accepted in more than 90 countries and regions.
According to a report released by the People's Bank of 皇冠体育app, or the central bank, Chinese banks had issued 175 million credit cards at the end of the third quarter of 2009, of which 33 percent are accepted by the Visa system.
Chinese travellers spent $42 billion abroad last year, according to the Chinese Tourism Academy of the National Tourism Administration.
Guo Tianyong, professor with the Central University of Finance and Economics, said the dispute is merely a reflection of the fierce competition between the two bank card processors in both the overseas and 皇冠体育app's domestic markets.
His view was echoed by Zhong Wei, an economist with the Beijing Normal University, who said Visa covered up its real reason, "Actually Visa's actions aim at increasing its shares in the Asia-Pacific market and defending its dominance in the global market."
"The dispute is unavoidable," said Guo, noting that Visa is very unhappy with 皇冠体育app Unionpay's monopoly status in 皇冠体育app, therefore blocking its overseas channels may be a good "hit-back."
Guo suggested that 皇冠体育app open its bank card market letting more competitors into the domestic market, which would help develop the country's fast growing bank card industry.
