Hong Kong (CNN Business)American Express just became the first US credit card company to get the green light to start building its own payments network in China.
In every other market around the world, AmEx processes transactions through its own network, whose hub is in Phoenix, Arizona. But in China, they have been handled by state-controlled payments giant China UnionPay.
Once AmEx has built its own network in China, it will be able to use it to process payments on AmEx branded cards and collect fees on far more transactions.

AmEx now has a shot at taking some of UnionPay’s business inside China.
Mastercard and Visa are also seeking permission to build their own networks after Beijing last year started letting foreign card companies apply for licenses.
“We continue to work closely with the Chinese government as we proceed through the application process,” a Visa spokesperson said.
Mastercard did not immediately respond to a request for comment on Friday.
