China's Periphery: The Contest Expanded From Fleets to Political Identity

Over the first weekend of July 2026, three events landed almost simultaneously. On July 5, Taiwan's Ministry of National Defense announced it was reinstating anti-communist patriotic education for military academy graduates — reversing a 2002 rename that had dropped the "anti-communist" label and explicitly teaching officers to identify their adversary by system, not just by flag ^[1]. On July 6, the Philippine Senate opened the impeachment trial of Vice President Sara Duterte ^[2]. The same day, China and Russia launched Joint Sea-2026 naval exercises from Qingdao, after a May summit that Xi Jinping and Vladimir Putin said placed bilateral ties at their highest point in history ^[3]. Three states on China's rim moved in a single weekend through three entirely different instruments: ideological rearmament, constitutional impeachment, and joint naval drills. That weekend is a compressed view of a pattern visible across the whole arc of China's periphery this spring and summer. Each state is reaching for whatever lever its own political system makes available — not a shared template — and the instruments vary so widely that no single word like "balancing" or "hedging" captures them. Taiwan's executive branch reinstated anti-communist education while its legislature remains deadlocked over a NT$1.25 trillion defense budget, with the Kuomintang internally split between legislators who want more spending than the ruling party proposed and those who want less ^[4]. The education order was an executive action that did not require that legislative fight. Its framing is explicit: the military is teaching graduates "why we fight, and for whom we fight" and establishing "a clear awareness of friend and foe" ^[1]. Separately, Taiwan's National Security Bureau launched a secure reporting website for Chinese nationals on June 14, with an AI video depicting a pervasive atmosphere of tension under China's "totalitarian regime" ^[5]. The adversary is named by its political character, not only its coast guard. The Philippines is working through a constitutional lever. The House impeached Vice President Duterte on May 10 in a 257-25 vote ^[6], and the Senate trial began seven weeks later. This is a domestic constitutional process, but it removes a figure from the Duterte family, which has championed closer ties with Beijing — a political outcome with foreign-policy consequences. Meanwhile the executive branch has been signing visiting-forces agreements with Japan, France, Canada, and New Zealand ^[7]. China sanctioned Defense Secretary Gilberto Teodoro Jr. and his family on June 11, banning them from mainland China, Hong Kong, and Macao, after he called China's maritime claims "the biggest fiction and lie" ^[7]. Japan's instrument is documentary and constitutional. The ruling Liberal Democratic Party approved a June 9 draft to revise three national security documents — raising defense spending, strengthening counterstrike capabilities, and building a government-led military export system ^[8]. Japan fired Type 88 surface-to-ship missiles in the South China Sea during U.S.-Philippines Balikatan exercises, deployed a destroyer through the Taiwan Strait, and revised lethal weapons export guidelines to the Philippines ^[9]. Japan and the Philippines also began formal maritime boundary negotiations east of Taiwan on June 4, explicitly to counter Chinese military expansion near Batan Island and the Senkakus — a diplomatic-legal instrument layered on top of the military one ^[10]. The hardware is still central; what changed is that the hardware now comes packaged in a revised postwar identity. Vietnam took yet another route. India signed a roughly $629 million deal to supply Vietnam with BrahMos supersonic cruise missiles, announced May 30 at the Shangri-La Dialogue ^[11]. Vietnam hardens against China not by building its own deterrent, not by signing a U.S. treaty, but by buying coastal-defense missiles from a non-Western third party — a procurement channel that lets a state strengthen its position without accepting the label of American client. The polymorphism runs in both directions. South Korea under President Lee Jae Myung reaffirmed the One-China policy on June 18, citing the 1992 Joint Communique ^[12]. Cambodia upgraded its China dialogue from a 2+2 to a 3+3 framework on April 22, adding interior and public-security ministries, and reaffirmed Belt and Road cooperation ^[13]. Both states moved toward Beijing through their own diplomatic instruments — the mirror image of the hardening states, using the same logic of system-specific levers. What converges across these states is not method and not even direction. It is terrain. The contest between China and its most assertive neighbors has expanded from military capacity to political legitimacy — and the states doing the most to contest that terrain are the ones whose disputes have turned ideological. China's foreign ministry has moved the Japan dispute onto historical-ideological ground. On the 80th anniversary of the Tokyo Trials, it accused Prime Minister Sanae Takaichi of "whitewashing war crimes" through textbook revisions, framed Japan's missile deployment and constitutional reform as "neo-militarism," and demanded Japan "accept the judgment of the Tokyo Trials" as the prerequisite for its postwar place in the international community ^[14]. China's spokesperson said Japan has "torn off the mask of pacifist country all by itself" and that "the international community must never allow Japanese militarism to return" ^[8]. A budget document is being framed as a betrayal of postwar identity. Japan's defense minister Shinjiro Koizumi rejected the label by inverting the frame. He pointed out that Japan has no nuclear weapons or strategic bombers while China does, called the accusation "cognitive warfare," and said that "if you tell a lie a hundred times it becomes the truth, we must refute what needs to be refuted" ^[15]. Japan is now contesting the narrative, not just buying more weapons. Between China, Japan, and Taiwan, each side now attacks the legitimacy of the other's political identity. China calls Japan's defense documents a revival of militarism. Taiwan's intelligence bureau calls China's system "totalitarian." Taiwan's military teaches its officers to name the "communist" as the enemy. Japan's defense minister calls China's framing "cognitive warfare." South Korea and Cambodia, by contrast, move toward Beijing through dry diplomatic language — communiques and framework upgrades — not identity attacks. That distinction matters for what comes next. A state that has bought BrahMos missiles can let the contract lapse. A future Philippine president inherits an impeachment that removed a China-aligned figure from the vice presidency through constitutional process. But a state that has re-educated its officer corps to identify the adversary ideologically, or redefined its postwar identity against a neighbor's historical narrative, has done something harder to reverse than a weapons contract — because the next government inherits the framing, not just the weapons. Missiles age. Curricula and historical narratives compound.
