MLM/Maoist parties like the Naxalites tend to be anti-China and still "serious" in that they wage protracted people's war, organize in real life, etc, but they are generally pro-USSR (Stalin era) and anti-NATO. I disagree with them theoretically but I will acknowledge that some of them have seen some degree of success when the material conditions of the countries they operate in are more agrarian (and as a result have more similarities with China's revolution, the closer they are the greater the degree of success).

ML parties generally agree with what you said, ie pro-USSR, pro-PRC, anti-NATO.
