A Chinese diplomat in Washington recently threatened that China would invade Taiwan if the U.S. Navy sent a ship to visit the democratic island, something that Congress has called upon the Pentagon to do in 2018. Is this just empty rhetoric? Or does it reflect Beijing's actual intentions? It's actually a bit of both.
According to leaked Chinese military documents ( analyzed here ), Taiwan stands to lose more from the rise of China as a twenty-first-century superpower than any other country in the world. Indeed, China's emergence as the world’s second largest political, economic and military power threatens the interests of many nations, but only Taiwan has its life at stake. Only Taiwan is held at risk of seeing its trade lines severed, its cities bombed and its shores invaded. Only Taiwan faces the possibility of having its president assassinated and its democracy destroyed. China's authoritarian government challenges many countries in many ways, but it only has war plans for the invasion and occupation of Taiwan.

China's rapid military buildup is focused on acquiring the capabilities needed to annex, or conquer, Taiwan. Chinese publications euphemistically call this "achieving national unification." The war plan for fighting a Taiwan invasion campaign is tattooed onto the PLA's corporate memory. It is something that has been indoctrinated and encoded into the minds of all top-level officers. For them, the interests of the regime, not the people of China, are paramount, and their "main strategic direction" (supreme objective) is to end Taiwan's life as a de facto independent country.
The good news is that the Chinese military almost certainly could not prosecute a full-scale invasion of Taiwan today and succeed. Even if a few hawkish generals were prepared to roll the dice, the costs and risks entailed by the war would be enormous and potentially fatal for the regime. PLA strategists know they still have a long way to go before they will be able to achieve their objective. The bad news is that China's leaders recognize the roadblocks in their path and will continue to invest heavily in strategic deception, intelligence collection, psychological warfare, joint training and advanced weapons. Barring countervailing efforts, their investments could result in a world-shaking conflict and an immense human tragedy.
War Plans and Politics
Any conflict between China and Taiwan will almost certainly involve America. The U.S. government does not recognize Chinese sovereignty over Taiwan and regards the island's sovereign status as unresolved. Moreover, the White House is legally obligated by the Taiwan Relations Act (TRA) to provide defensive arms and services to Taiwan, and to maintain the U.S. military's capacity to respond to any Chinese use of force against the island. Should China seek to blockade, bomb and invade Taiwan, the United States would be compelled to help its democratic friend.
While not as binding as a mutual defense treaty, the TRA (U.S. Public Law 96-8) makes it clear that Washington is likely to intervene if China uses force. In addition to being a matter of principle and honor, the United States needs Taiwan for geostrategic reasons. It has become increasingly clear to American strategists that China has embarked on a long and intense competition for dominance over the Indo-Pacific. Taiwan is at the geographic and political heart of this competition. Maritime tensions in the East China Sea and the South China Sea, while serious, pale in comparison to this flashpoint.
Separated by the Taiwan Strait for sixty-eight years and counting, China and Taiwan each exercise authority only over the territory under their respective control. Neither is subordinate to the other, and neither recognizes the legality of the other. From the perspective of Beijing, the Chinese Civil War never ended. As a result, the two governments have no official relationship and are still ideologically and militarily hostile. China's desire to annex Taiwan keeps cross-Strait relations perpetually strained.
While acknowledging the huge risks entailed, Chinese military writings use many arguments to justify the invasion of Taiwan. They point out that critical geostrategic issues are at stake. Internal PLA materials argue that Taiwan sits in a controlling position along China's eastern seaboard, making it a gateway to the Western Pacific and the Indian Ocean. They assert that since the great majority of China’s shipping traffic passes through the Strait, it is a vital area affecting the security of their coastline, national economic growth, and future prosperity.
The Course Book on the Taiwan Strait's Military Geography is a restricted-access PLA manual, used to teach senior officer seminars in Beijing. It warns readers that an external military might one day use Taiwan to cut-off China’s trade lines, hinting that the island could be used as a military base by the United States to blockade China and undermine its rapid rise to great power status. On this basis, the manual argues that physical control over the island is vital for safeguarding against foreign blockades. China’s seaborne oil imports, which pass through the Strait, are highly vulnerable, “so protecting the security of this strategic maritime passageway is not just a military activity alone, but rather an act of national strategy.”
