According to Bloomberg:

Under the China program, retail staff at Apple outlets will assess an iPhone's condition before offering store credit for those originally bought in Greater China, the person said. Foxconn will buy the phone directly without Apple ever taking ownership, according to the person.

Foxconn will repair the devices if needed and then sell them through its e-commerce sites eFeihu and FLNet, and through Alibaba Group Holding Ltd.'s Taobao online store, one person said. Foxconn also is in talks to sell the iPhones through physical stores and may take the trade-in program online in the future, the person said.

For now, the trade-in program in the country will reportedly be applicable only to iPhones, unlike other markets where Apple is said to roll out similar offers for Android smartphones.

The program is set to launch as early as March 31 in China, and is the latest of many initiatives targeted at expanding Apple's presence in the region. Earlier this year, the Cupertino giant opened five new stores in the country.
