The New York Times reports that the Central Intelligence Agency faced one of its worst intelligence gathering setbacks in decades when many of its informants in China were killed or imprisoned between 2010 and 2012. To this day, it is unknown how the identities of the informants were compromised:
From the final weeks of 2010 through the end of 2012, according to former American officials, the Chinese killed at least a dozen of the C.I.A.'s sources. According to three of the officials, one was shot in front of his colleagues in the courtyard of a government building — a message to others who might have been working for the C.I.A.
Still others were put in jail. All told, the Chinese killed or imprisoned 18 to 20 of the C.I.A.'s sources in China, according to two former senior American officials, effectively unraveling a network that had taken years to build.
Assessing the fallout from an exposed spy operation can be difficult, but the episode was considered particularly damaging. The number of American assets lost in China, officials said, rivaled those lost in the Soviet Union and Russia during the betrayals of both Aldrich Ames and Robert Hanssen, formerly of the C.I.A. and the F.B.I., who divulged intelligence operations to Moscow for years.
The previously unreported episode shows how successful the Chinese were in disrupting American spying efforts and stealing secrets years before a well-publicized breach in 2015 gave Beijing access to thousands of government personnel records, including intelligence contractors. The C.I.A. considers spying in China one of its top priorities, but the country's extensive security apparatus makes it exceptionally hard for Western spy services to develop sources there.

Last year, China warned government officials to watch out for spies - and not fall in love with them
This CIA story really helps put that "Don't date a foreigner!" campaign in perspective. You don't want to see your significant other bleeding out in the street, do you? DO YOU?!

Edward Snowden once worked for the CIA, yet the information he leaked was about the NSA.

1) I could've sworn that these recent NSA tool leaks weren't from Snowden, or, at least, it's been confirmed that there has been another leaker to Wikileaks other than he since his big splash.
2) Wouldn't him leaking info about the NSA for the CIA necessitate him being a CIA employee previously?

You had some speculation about "infighting" that you said was off-topic, so I offered some additional speculation. Edward Snowden did work for the CIA:

I didn't mean to suggest that he was behind the recent leaks. I was alluding to the documents he released beginning in 2013. They increased public awareness of the NSA and, I would say, brought it into disrepute.
