China just showed how easily one of its massive drills around Taiwan could escalate into something worse

• China conducted massive drills around Taiwan last month, surrounding the island.
• It demonstrated how easily China can launch a drill with little to no warning.
• These exercises could easily escalate.

Last month, China conducted large-scale military exercises around Taiwan with the intent to send a message.

As elements of the Chinese joint force surrounded the island democracy for the two-day event, it became clear how easily one of these massive drills could escalate into conflict, giving China the ability to launch a blockade or quarantine of the island with little to no warning.

The Chinese armed forces have been able to "essentially start mounting an increased tempo of these large-scale drills that have a lot of the makings of a blockade," Tom Shugart, a former US Navy officer and current adjunct senior fellow at the Center for a New American Security think tank, said.

He added that the May exercise showed that China's fleet "is very well suited" for a blockade or quarantine of Taiwan.

The Department of Defense has identified a blockade as a possibility, noting in its most recent report on the Chinese military that "PLA writings describe a Joint Blockade Campaign in which the PRC would employ blockades of maritime and air traffic, including a cut-off of Taiwan's vital imports, to force Taiwan's capitulation."

If effectively executed, such action would potentially have immediate and dire consequences for Taiwan's economy, cutting off its trade and shipping. Such a move could force its military into action without necessarily triggering a military response from the US and its allies, possibly leaving it to stand alone.

After the most recent Chinese military drills, US Indo-Pacific Commander Adm. Samuel Paparo said the US observed the exercises closely, learning from them and assessing that they "looked like a rehearsal" for a military action against Taiwan.

There has long been speculation that the US would respond with force to a Chinese invasion of Taiwan, but the US response in the case of a blockade or quarantine, actions short of an amphibious assault, remains unclear.

China's recent exercise "Joint Sword" focused on "joint sea-air combat readiness patrols, joint seizure of comprehensive battlefield control, and joint precision strikes on key targets," according to Chinese state media reports. The training included mock strikes by fighter jets with live ammunition and drills with various naval vessels, including frigates and destroyers.

The exercise appeared similar , in many respects, to the drills in April 2023 and notably tamer than the August 2022 drills, which occurred after then-US Speaker of the House Nancy Pelosi visited Taiwan. The latest exercise lasted only two days compared to seven.

And the Chinese-declared zones for May's drills were also only along the edges of Taiwan's contiguous zone, compared to the 2022 drills, which featured large exclusion zones that crossed into Taiwan's airspace and waters. During those exercises, China also fired missiles over the island, a highly provocative action.

Yet the latest exercise came with almost no warning, suggesting China can continue conducting such drills surrounding Taiwan at its leisure and prepare for and launch them with minimal notice.

"This is less a distinct operation and more just a step up in tempo," Mick Ryan, a retired Australian major general and strategist focusing on evolutions in warfare, told BI.

"What this shows us," Ryan said, "is that they have an ongoing operation which they can kind of turn the temperature up and down on with more fidelity now than they have been able to previously."

That would help China, were it to suddenly pursue a more aggressive course, maintain the element of surprise, which its war doctrine emphasizes as a key component of its fighting plans.

By increasing the frequency of and normalizing its military presence around Taiwan, China is adopting what experts and military officials, including retired Adm. John Aquilino, the former head of US INDOPACOM, have referred to as a "boiling frog" strategy .

The strategy essentially involves stepping up and maintaining aggression in the area so that the critical point when China actually decides to enact a blockade or quarantine is less discernible.

Such an event would be an act of war, but it still leaves the US and its allies in an odd place, weighing options as to how to respond, especially if it is short of large-scale violence.

Think tanks have played out war games of different Taiwan invasion scenarios , some of which have resulted in heavy losses for US, Japanese, and South Korean forces , as well as China's military. An all-out invasion isn't the only option though, as the recent drills demonstrated.

"The exercise really highlights the vulnerability of Taiwan to a lot of other scenarios than just invasion," Shugart said, noting that regardless of when or if one of these large drills transitions into a blockade, the most concerning issues are how easily that could occur and how China continues to use its military presence to create a new normal in the area.

And within that new norm, China could create a situation in which Taiwan, exhausted and overwhelmed, is fractured, its resolve ultimately degraded.

Per a report published last month by war experts from the American Enterprise Institute and the Institute for the Study of War, an aggressive Chinese coercion campaign — short of war and more likely than a full-scale invasion — would involve boosting the Chinese military presence and pressure around Taiwan and possibly even a blockade or quarantine.

The report asserted that the US is ill-equipped for such an event, instead overly preoccupied with preparing for a potential amphibious assault , and that "Taiwan is strategically vital to the larger US-led coalition to contain" China, arguing that a "US-friendly Taiwan links America's allies in the northwestern Pacific with US partners and allies to the south."

However, a China-controlled Taiwan "would become a springboard for further PRC aggression and would seriously compromise the US-led coalition's ability to operate cohesively."
