"Not a viable solution."

Difficult certainly. But with satellites and spies, we could determine which oil tankers & cargo ships with food are headed to China then turn them around.

Also the above combined with export embargo would aid in hampering China.
US & Canada make up 40% of imported foodstuffs.
And there is a possibility of the US influencing Bahrain, Qatar & Saudi Arabia to cut or stop oil exports to China. Some of the China oil could be diverted to other markets.
