You don't need a repeater to test a Chinese GSM phone in States, because you are not going to re-translate the signal from China to US.

You need a Radio Communication Tester:

R&S?CMU200 Universal Radio Communication Tester (Rohde & Schwarz International - Products - Test & Measurement - Wireless Communications Testers & Systems)
E6392B GSM (GPRS) Mobile Station Test Set [Obsolete] | Agilent
