Beijing's Best Weapon Against Taiwan Isn't Missiles — It's the KMT's Legislative Veto

On Tuesday, KMT Chairwoman Cheng Li-wun stepped off a plane in Shanghai to begin what she called a "journey for peace"¹ — a six-day visit to mainland China, the first by a sitting KMT leader in a decade, at the personal invitation of Xi Jinping. She visited Sun Yat-sen's mausoleum in Nanjing, dined with Taiwan Affairs Office head Song Tao, and is expected to meet Xi himself in Beijing before the trip concludes. The imagery is unmistakable: the leader of Taiwan's main opposition party, received with state-level hospitality by a government that refuses to even speak to Taiwan's elected president, whom it labels a "separatist."

The conventional take on this trip will split along predictable lines. Supporters see a courageous peace effort. Critics see a Beijing propaganda stunt. I think both readings miss the more important thing happening in plain sight. This trip is not really about what happens in Beijing. It is about what is already happening in Taipei's legislature.

Start with the defense budget. In late November 2025, President Lai Ching-te proposed an NT$1.25 trillion (roughly $40 billion) special defense budget³ to fund missile defenses, long-range strike weapons, drones, and a multi-layered air defense system called "T-Dome" over eight years. The KMT-TPP legislative coalition has blocked this budget more than ten times⁴. They advanced a slimmed-down alternative capped at roughly $12 billion — cutting 70 percent of the original funding and jettisoning the T-Dome system entirely. In 2025, the same coalition passed the largest series of cuts to the Taiwanese government budget in history⁵, scrapping close to one-third of operational spending, including defense.

Now hold that fact in your mind while watching Cheng's trip. On the same week that a U.S. senator visited Taipei to urge the legislature to pass the defense budget, and the same week U.S. Senator Dan Sullivan wrote on X that "shortchanging Taiwan's defense to kowtow to the CCP is playing with fire," the leader of the party doing the blocking was toasting with CCP officials in Shanghai⁶. As Sullivan himself put it: "It doesn't take a genius to figure out what's going on here."⁷

I want to be precise about what I think Beijing's strategy is and is not. It is not an effort to win hearts and minds in Taiwan. On that metric, Beijing is losing badly and has been for decades. The Election Study Center at National Chengchi University⁸ has tracked Taiwanese identity since 1992. Exclusive "Taiwanese" self-identification has risen from about 17.6% to roughly 60-64% over that period. "Chinese only" identification has collapsed to around 3%. A Taiwan Public Opinion Foundation survey from October 2025² found only 13.9% of respondents supported unification, versus 44.3% supporting independence. That trend is real, it is generational, and it is not reversing.

But here is the thing the identity data obscures: stated preferences and actionable outcomes are different variables. You can have an electorate that overwhelmingly identifies as Taiwanese and overwhelmingly rejects unification and still not get a coherent defense posture — if the legislature is gridlocked. And that is exactly where Taiwan finds itself right now. The DPP holds the presidency but the KMT and TPP control the legislature, 52 and 8 seats to the DPP's 51. The result is a government that wants to arm itself but cannot get its own parliament to approve the budget.

This is where Beijing's strategy gets sophisticated. The KMT does not need to win the presidency for Beijing's purposes. It needs to maintain enough legislative seats to function as a veto player on defense and sovereignty questions. And that is a much lower bar than winning national elections. The KMT remains strong in local politics — it "continues to perform well in local elections – thanks to its deep political networks and long history in Taiwan," as Al Jazeera's reporting notes². Those networks translate into legislative seats even as presidential vote share declines.

The immediate strategic payoff is concrete: with the defense budget stalled, Taiwan is not acquiring the weapons systems that the U.S. has already approved for sale. The December 2025 U.S. arms package was valued at over $11 billion¹¹, including medium-range missiles, HIMARS, howitzers, and drones. Several of those items have already reached the contracting stage — what's called Letter of Offer and Acceptance — and those offers have expiration dates¹⁰. If the budget impasse continues, Taiwan could miss the window to close deals on weapons its own military says it urgently needs.

Cheng's visit to Beijing amplifies this dynamic in a way that is genuinely clever. By positioning the KMT as the "peace" party, Beijing gives KMT legislators domestic political cover for blocking defense spending. It's not obstruction, the argument goes — it's responsible statesmanship. "Peace cannot possibly be achieved through defence capabilities alone," Cheng told foreign reporters, and "political efforts were equally indispensable." That framing lets the KMT hold up the defense budget while pointing to photo ops in Nanjing as evidence that their approach is working.

The strongest counterargument I can see is this: Beijing's coercive behavior — the military drills, the encirclement exercises in December 2025, the record 3,570 Chinese military aircraft incursions in 2025¹² — is itself the primary driver of Taiwanese identity consolidation. Every missile drill pushes more Taiwanese to identify as Taiwanese, not Chinese. Beijing is simultaneously cultivating the KMT and undermining its electoral viability. That's a genuine structural tension, and over 20-30 years it may well doom the strategy.

But the near-term problem is more acute than the long-term trend line suggests. Two developments are creating what Yen Wei-ting, a researcher at Academia Sinica, calls "a political window"¹ for Cheng's peace positioning. First, Trump's mercurial approach to Taiwan — including suggestions he'd discuss arms sales with Xi at their May summit — has eroded trust in the American security guarantee. Second, the wars in Ukraine, Gaza, and Iran have left many Taiwanese questioning whether a distracted U.S. would actually show up. These are not permanent conditions, but they are conditions that the KMT can exploit right now, and Beijing knows it.

There's also the economic dimension, though it's weaker than it was. In 2025, the United States became Taiwan's biggest export market for the first time in 26 years⁹, accounting for 30.9% of total exports. China and Hong Kong dropped to 26.6%. That's a dramatic shift from the 42-45% dependency of just a few years ago. Taiwan's export diversification is real and accelerating, powered by AI-driven semiconductor demand. This materially weakens one leg of Beijing's leverage.

But it doesn't weaken the legislative leg. And that's the one doing the most damage right now. Brookings notes that the KMT-controlled legislature has authorized the Ministry of Defense to sign the Letters of Offer and Acceptance for some items, but the overall funding remains deeply contested¹⁰. The TPP coalition partner is itself in disarray — founder Ko Wen-je was sentenced to 17 years in prison for corruption¹³ in March 2026 — but the KMT-TPP legislative alliance persists on the defense budget question despite that instability.

My assessment: Beijing's strategy of engaging Taiwan's opposition is not going to produce reunification. The identity trends are too strong, the demographic math too unfavorable, the Taiwanese public too hostile to "one country, two systems" (repeatedly polling above 80% opposed). But reunification was never the near-term goal. The goal is preventing Taiwan from consolidating a deterrence posture that would make coercion prohibitively costly. On that narrower, more achievable metric, the strategy is working. A Taiwan that cannot pass its own defense budget is a Taiwan that is weaker than its stated preferences suggest it should be.

What to watch next: the KMT's counterproposal defense budget will move through the legislature in the coming weeks. If it passes at the reduced $12 billion level, the practical effect is that Taiwan's T-Dome air defense system and major domestic defense industrial investments get shelved. Watch also for any party-to-party agreements signed during Cheng's trip — particularly on agricultural trade or municipal exchanges between KMT-controlled localities and Chinese cities. These would not be binding on Taiwan's government, but they would deepen the institutional connections that make Beijing's parallel diplomacy harder to dismantle. And watch November's local elections: if the KMT performs well, Beijing's strategy gets another legislative cycle of veto power. If the KMT's Beijing embrace costs it at the ballot box, the strategy's shelf life shortens considerably.
