Are Clients connecting to PoPs in China and Vietnam still limited to 20Mbps maximum throughput?

Cato KB "Supported Throughput for Cato SDP Clients" states that remote client users connecting to PoPs in China and Vietnam are limited to 20Mbps maximum throughput. Is this still the case? If so, why? Are there plans for this restriction to be lifted in the roadmap?

This is a recurring question for customers with distributed footprint across China and Vietnam.
