I am not sure even the Chinese know exactly what “OBOR” will be.
Xi jinping has proven to everyone that China is done “reforming.” They will of course have a large private sector, and even the many massive state-run industries will face “the market” - but the CCP and Chinese Government will remain firmly in control of all policy.
As such, they will continue to produce a lot of stuff communists and central planners love - steel, cement, ships, trucks, etc... this needs to go somewhere, and China’s neighbors will get it cheap - with some strings attached, of course. that is OBOR.
“As such, they will continue to produce a lot of stuff communists and central planners love - steel, cement, ships, trucks, etc...”
You forgot cars, bullet trains, computing, electronics, appliances, internet commerce, quantum communications, nuclear power, solar, spaceships etc.
