In Secret Meeting, China Acknowledged Role in U.S. Infrastructure Hacks
A senior Chinese official linked intrusions to escalating U.S. support for Taiwan

Yes, we set up some of the northern Philippine islands and coordinated with Japan, etc., so we can cover the backside of Taiwan should hostilities break out. Singapore has scaled down its military exercises in Taiwan.

China doesn't want to cross swords with the US on Taiwan and neither do we, thus the strategic ambiguity.
