BEIJING/HONG KONG (Reuters) -China may respond to the U.S. shooting down its suspected spy balloon after warning of "serious repercussions", but analysts say any move will likely be finely calibrated to keep from worsening ties that both sides have been seeking to repair. Regional analysts and diplomats are closely watching China's response after a U.S. fighter jet shot down the balloon - which Beijing says was an errant weather-monitoring craft - in the Atlantic off South Carolina on Saturday. China on Sunday condemned the attack as an "over-reaction", saying it reserved the right to use the necessary means to deal with "similar situations", without elaborating.
