The Chinese foreign ministry said in a statement on Friday that the suspensions were among eight specific measures against the US that Beijing is adopting.
Dialogue between area commanders and defence department heads will be cancelled, along with talks on military maritime safety, the foreign ministry said.
Cooperation on returning illegal immigrants, criminal investigations, transnational crime and illegal drugs will also be suspended.
China is also continuing with the unprecedented military exercises in six zones surrounding Taiwan that began on Thursday morning, which have led to disruption for trade routes and international flights as Taipei looks for alternate options.
Missiles were also fired directly over the Taiwanese capital on Friday, defence officials told state media, a significant escalation.
China opposes the self-governing island having its own engagements with foreign governments, saying such interactions amount to international support for the Taiwanese government to seek to formalise its independence.
