If evergrande is the parent company, I don't think a restructuring of its own debt affects the debt of its subs, so the chinese sub would still be liable for the funding it borrowed from the parent unless it is itself restructured. If you borrow money from a bank and that bank goes bust, you still owe the full balance based on the initially agreed repayment schedule, it is just that your loan is now an asset contributing to the recovery of the bank's own creditors.
