Chinese online travel agent Ctrip.com International Ltd. removed an option from its website that allowed customers to pay using Turkish lira, Reuters reported Aug. 13, citing a spokeswoman for the company.

The move came after some customers who paid in Turkish lira sought to exploit fluctuations in the currency by asking for refunds in yuan, the spokeswoman reportedly said.

Turkey's central bank on Aug. 13 reduce banks' lira reserve requirement ratios in an attempt to tackle the country's deepening currency crisis.
