I have been reading a blog by James Seng, who is a Singapore-based wholesale sourcing agent for medical supplies exported out of China. He seems to have backed into this role (for years he was a high-level expert on Internet architecture and governance, credited with bringing e-commerce to China) and is now ideally placed to provide insight into the workings of supply chains out of China in a suddenly critical area.
Seng is writing a series of posts on subjects such as N95 masks and ventilators. Each one is a deep dive into the intricacies of international manufacturing standards, industrial supply chains, Chinese factories, black-market speculators, and much more. Absolutely fascinating stuff – and, in the case of the ventilators, infuriating.
