Apparently the next launch from Xichang afte APStar-9 is the other secret payload we have guessed earlier - one Chinese forum members claims that it is "ChinaSat 2C". Based on the comments from issuing launch day mail covers, it seems that it will be launched in the last days of this month or early November.

Any idea on Chinasat-2C intended slot?
BTW I got the impression that tles for Chinasat-22A and Chinasat-20 could be mixed up...
Chinasat-22A/29398/ 2006-038A (DFH-3) present orbit inclination: 4.70°
Chinasat-20/ 28082/ 2003-052A (DFH-3) present orbit inclination: 2.29°

I believe this thread should be combined into this one: https://forum.nasaspaceflight.com/index.php?topic=30335.0
Do you believe ZX-2C and ZX-M are the same satellite?
There's just too little info around either satellites to make any conclusions, although given how ZX-M mysteriously appeared then disappeared, no wonder some people are trying to fit it with one of the military comsat birds. However there isn't any proof of this.

According to at least one local source this launch will occur on November 3 GMT (4th local time).

I don't know how on earth that could happen, but someone has posted a snipped photo of the internal launch manual! That shows the launch time as 16:25 UTC.

Any hint about what type of satellite ZX-2C is? I'm assuming this is a military communications satellite, but its a Shentong-2, a Fenghuo-2? Any other bird?

If I have to guess, maybe it is a continuation of the series starting with ZX-2A, and ZX-1C will follow ZX-1A? But with the Chinese, who knows?

Reports of launch success have come from a source on Weibo that has been very reliable for the last 6-7 launches. Take it with a grain of salt while I wait for official news which often come hours late these days.

Chinasat-22A/29398/ 2006-038A (DFH-3) present orbit inclination: 4.70°
Chinasat-20/ 28082/ 2003-052A (DFH-3) present orbit inclination: 2.29°
Short answer is that 28082/ZX-20 lost its north-south control capability in Nov 2012, nine years after launch
while 29398/ZX-22A lost it in Dec 2009, only three years after launch. Thus, ZX-22A has a larger inclination today even if she was launched later.
Long answer includes some thoughts of the strange event in June 2008, when, according to TLEs, on June 24 object 28082 was at 103.25° but on June 25 it jumped to 97.95 E, and object 29398 did the opposite. Naturally you can't move a satellite by 5 degrees in a day, so I was quite sure that the USSTRATCOM had somehow exchanged the identities of the two spacecraft and continued to track ZX-20 as 29038 and ZX-22A as 28082 from June 25, 2008.
But I was wrong; in a CAST news item
http://www.cast.cn/CastCn/Show.asp?ArticleID=40088 (issued more than three years later) you may see that between June 13 and Jun 17, 2008, ZX-20 and XZ-22A has indeed exchanged their orbital positions "due to the needs of users". So, 28082 = ZX-20 did go from 103.25° to 97.95° and 23938 = ZX-22A moved from 97.95° to 103.25°E. Trends in inclinations of the two satellites exhibited before June 13 and after June 25, confirmed this claim.
Elsets for the two from Jun 13 to Jun 24, 2008, probably were estimates based on some model and not on observations. When the USSTRATCOM discovered the exchange, the elsets from June 25 on were issued for new positions. (We've observed another example of this process with one of the Ekspress AM satellites recently.)
Since then, in June 2013 ZX-20 returned to 103°E and earlier ZX-22 moved to 101.5°E.
