Think you’re safe with your supply contracts in China? Got signed confirmation of orders? Got emails confirming everything? Supplier signed your legal contract?
Signatures are virtually worthless if you have a dispute that goes to court in China. Likewise emails.
What you need is the chop.
Documents with the legal chop are the only safe form of evidence if you need to go to court in China.
So make sure you get all supply contracts chopped by the other party.
