合资各方在注册地开户银行出据的资信证明 = certificates of capital brought ins and approved credit lines issued by the local bank where the partners opened their account for the joint venture

FYI

资信证明, literally means "credit standing certificate", which is very similar to the credit standing report by Dun&Bradstreet. Here, 资信证明 is just a certificate issued by a bank to the effect that as of the date of the certificate, the customer has always maintained a good relationship with the bank, enjoyed a sound financial strength, without any misconduct, default, or negligence during its dealings with the bank, and no such bad acts with any other parties as far as the bank knows.
I myself were involved in issuing such certificates to customers many years ago.

One of the documents required to be submitted to the PRC competent goverment authorities for setting up a Sino-foreign joint venture in the PRC is the ""Certificate of Credibility" or "Certificate of Standing"", which shall be issued by the bank. In practice, it is also refferred as "bank reference letter". Usually, this document will set out the assessment of the client's credibility/standing given by the bank based on the operating track record of the subject bank account.
