Ukraine’s belated decision on March 29 to stop supplying weapons and military equipment to Russia, a month after its troops seized the Crimean peninsula, is likely to lead to the cancellation of numerous international contracts signed by Moscow. The decision is likely to impede Russia’s military-defense industry significantly.

As the second largest exporter of arms with the world’s third military budget of $91 billion, Russia is extremely dependent on Ukrainian supplies, which accounts for 87 percent of its military imports, according to the Stockholm International Research Institute.
