It's not like it's spelled out in the contract: "we will use free loans from the Chinese govt to take your tech, undercut your markets and put you out of business. We have no intentions of letting your business thrive and survive."
We're getting smarter about it but this is way of doing business is very foreign to the West. The West sees investors as capital assets and not active market players. When Peter Thiel invests in a company he is not looking to spin up his own competing clone. He wants the business to succeed. Not so in China, who has a vested interest in running US businesses into the ground.
