Except we are not at war with China (No declared war!) so, it doesn’t meet the Constitutional definition of treason. Sedition, more bribery, possible violations of the Espionage Act, failure to register as a foreign agent, etc. yes but doesn’t meet the treason threshold.
The Founding Fathers deliberately set the bar for treason very high!
Except the Constitution doesn’t say we must declare war. It says “OR in adhering to their Enemies, giving them Aid and Comfort”. The case could be made that China is indeed our enemy and he certainly has provided them aid and comfort and, at our expense.
