Can I get China visa ?

Currently, China is only open for emergencies, family reunion, overseas students and employees. In your situation, it's not easy to get a visa. But the border is expected to open soon, when you can apply for a tourist visa to enter.

China is open for business visa since last year You need invitation letter from chinese company stating period coming to china and expected dates,copy of the inviting company license plus bank statment of you in usa ,passport copy, picture,copy of latest chinese visa and entry exit stamps then apply online for M visa
If you have your own registered company in china and ur residency and work permit expired , then u need to apply for Z visa which need other documents requirements

Regarding your bank issue , be sure you bring the passport that registered in the bank last time.and if it is expired ,you still need to bring it to the bank and submit with your new passport to update your bank file.
