Some of y'all may already know that China has their own set of charging standards for AC and DC charging. Tesla had to redesign their car to support this: Tesla unveils new dual connector charge port design for Model S and Model X The DC port is new, and the /C port is a reversed Type 2 port. Now while reading the news about Chademo's meeting, it seems that China is working on a more higher powered DC port. From here (read page 43 onward): http://www.chademo.com/wp2016/wp-content/japan-uploads/2018GA/CHAdeMO2018GA.pdf It looks like the SE side may be backwards compatible with the EV side that use the other GB/T DC standard. It also seems like based on google translate that Japan and China may try to have some compatibility around the DC side of things. 900 kW max charging does sound like a lot, though it would work great for something like the Tesla Semi.
