# China

> What Coverbase asks a supplier in China for, and which of those rules block a submission.

[User guides](/user-guides/overview) / [Supplier countries](/user-guides/supplier-countries/overview)

A supplier whose bank account is held in China sees the fields below. The country is chosen on the form, and changing it changes the fields, so a supplier is never asked for a detail their country does not use.

<Note>
  Some rules on this page could not be confirmed against a primary source. Those are applied as warnings rather than rejections.
