China has suspended regulations requiring companies that sell computer equipment to Chinese banks to reveal their source code, submit to audits, and build back doors into hardware and software in order to allow for third-party monitoring.  In a letter issued to banks earlier this month, the China Banking Regulatory Commission and the Ministry of Industry and Information Technology called for them to “suspend implementation” of the rules, which have been criticized as a protectionist move that would have prevented banks from using technology from non-Chinese companies.
