"To avoid a breakdown of deterrence, China must believe there are actions that could lead to a US response and that costs will be imposed if China takes those actions," the recommendation stipulated in the full 551-page report reads. "A lack of clarity in US policy could contribute to a deterrence failure if Chinese leaders interpret that policy to mean opportunistic aggression against Taiwan might not provoke a quick or decisive U.S. response."
"Moreover, US officials have suggested that an unprovoked Chinese attack on Taiwan might result in US intervention," they added, "but they have not specified how the United States would react to other belligerent Chinese activities below that threshold, such as a blockade or coercive activities in the gray zone."
