'US Secretary of State Mike Pompeo has certified to Congress that Hong Kong no longer merits special treatment under US law.
The declaration could have far-reaching implications for US-Hong Kong trade.
"No reasonable person can assert today that Hong Kong maintains a high degree of autonomy from China, given facts on the ground," he said in a statement.
It comes hours before Beijing is expected to impose a controversial new security law on the territory.
The security law was "only the latest in a series of actions that fundamentally undermine Hong Kong's autonomy and freedoms," Mr Pompeo said.
"It is now clear that China is modelling Hong Kong after itself," he added.'
