I don't think making sure everyone is "on the right track" should be a top priority in deciding support/alliances.

Any communist project must first be anti-imperialist and anti-fascist until those forces no longer have a stranglehold on geopolitics.

Even if it means supporting a country with the "wrong" politics, it's still important to have a bulwark against US imperial hegemony.

This certainly has been the viewpoint adopted by modern China, and I think this stance deserves credit for enabling the CCP to survive into this millennia, unlike many of the failed socialist projects of the 20th century.

This is a great article on China's long term strategy.

Excerpt:

Contradictions in the foreign policies of the CPC include those which result from the strict non-interference in the affairs of foreign states, which has characterised Chinese foreign relations for thousands of years, and the prioritising of larger international trade relationships over ideological conflicts. One example is unscrupulous business deals with right-wing governments, such as Saudi Arabia or Israel. The “live and let live” ethic of this modus operandi even applies to ideological enemies: China also trades with the biggest terrorist organisation in the world, the USA, without even criticising its long list of illegal wars and heinous crimes against humanity (although this may be changing). Another is not supporting local leftist struggles in partner nations, such as guerrilla Maoist insurrections in SE Asia, if it might jeopardise trade relations with state entities. If the temporary “ethical net-losses” of these contradictions lead to larger “net-gains” and positive results in the long term, they are calculated as worthwhile or unavoidable.

The CPC understands that national leaders and ruling parties are fickle and ephemeral, but development and the improvement of material conditions will have long lasting effects. Creating a more balanced global playing field is the long game, which will create the conditions necessary for systemic change in each country, by their own agency. The phrase “Socialism With Chinese Characteristics” may have seemed clumsy and overly wordy at first, but the world will slowly come to understand its internationalist meaning, and that it is this way for a very specific reason: in anticipation of Socialism with Indian Characteristics, Socialism with French Characteristics, Socialism with USAmerican Characteristics, and 1000 socialisms with local characteristics to bloom.
