Much of China's BRI projects are designed to avoid the Straits of Malacca shipping bottleneck of which 50% of China's supplies and deliveries pass through.
All the USA has to do is to block the Straits and China is snookered Traewise & China knows that. Even India hinted at that a onth ago.
Consequently China's BRI is building the trans Asia railway which will reduce shipping time from 6 weeks to 14 days to Europe, Is building a port in SW Pakistan close to the Gulf with North/South Pakistan roads, rail & pipelines to supplt SW China
It is doing the same thing in Myanmar (hence the relocation of the Rohingya)
These projects are costing Trillions just to defend China's trade and its economy against US aggression.
Rather than the USA bolster up its own industry & economy, it is trying to stymie China's by attacking its Made In China 2025 & the BRI. and blaming China for America,s economic and social woes.
