Trend of PRC exports to RU still increasing MoM, occasional pause i.e. current hiccups to figure out system to evade threat of secondary sanctions. Many new PRC/RU traders still new to process / being cheap / lazy thinking they can skip middle men.
As for ball bearings, one would hope 2 years is enough for RU to setup their own plants. PRC not just selling them inputs, RU getting capita equipment to build their manufacturing base.
