Strengthen the military in the short term
Your military will be able to produce more tanks, weapons, fighter jets, and defense systems than it normally would have. If Russia were to invade, they would still be able to win a conflict because they have one of the best militaries in the world, but your military will be strong enough to both lengthen the war and raise the costs of war. Even if the communist bloc was weakened, the military buildup may deter the Russians from invading. This military buildup would come at the opportunity cost of investing in your developing domestic industries.
You have chosen a mixed economic liberalist approach to developing your economy. Your infant domestic industries are fully open to domestic volatility but will be shielded from international competition. Unfortunately, your economy will not benefit from absolute gains and access to more markets and resources. If your industries innovate and develop favorably, then, over time, you will be able to reap relative gains from integrating into an open world economy. In the short term, your refusal to join all of those institutions isolated Chechnya from the US-led capitalist bloc. Therefore, you do not have a security guarantee from a great power.
Your choice to depend upon Russia for capital and cheap energy has resulted in a significant strengthening of your military. However, the long-term economic sustainability of your military growth is in question because of your dependency on Russia for continued investment and artificially low costs of production.
Recently, two states succumbed to the capitalist bloc's pressure and switched from communist economic systems to capitalist economic systems. This has emboldened Russia, who have cut off their unconditional loans and cheap energy supplies to you. Russia has demanded you pay them back in the short term and has threatened to use force if necessary. Still, you have made the Russian decision to invade Chechnya much more difficult because your strengthened military has significantly raised the costs of war.
For now, the Russians decide not to invade Chechnya because your modernized military has raised the costs of war too high. If the situation in Russia continues to deteriorate, Chechnya may be in trouble. You have had to make some tough decisions between economic and military investment, but you managed to successfully avoid a potential crisis in the short term.
