dose this support China region?

I try to test Z3 in China Region, the test is failed cause by the 403 Forbidden.
I replace the bucket with Tokyo region, the test can be success.

Traceback (most recent call last):
File "/usr/local/bin/z3", line 11, in

If boto supports the china region, then z3 should as well.
Also according to the FAQ https://www.amazonaws.cn/en/about-aws/china/faqs/ you need a separate set of credentials to access AWS China.
