In his first foreign television interview since taking office, President William Lai (賴清德) issued a sobering warning about the threat China poses to global stability. Speaking with Japanese pop icon Sho Sakurai on his News Zero show, Lai said that Beijing’s ambition to change the rules-based international order begins with its goal of annexing Taiwan. A conflict across the Taiwan Strait would devastate global supply chains, underscoring the urgent need for deterrence and international unity, he said.
The interviewer also caught people’s attention. Sho brought an unconventional, but powerful blend of celebrity and soft power into the Presidential Office. His presence made complex issues — defense readiness, conscription reforms and regional geopolitics — accessible to younger audiences often disengaged from matters of national security.
Beneath the polished broadcast lay a sobering reality: Japan’s concern for Taiwan’s security has never been more visible, vocal or strategic. The evolving partnership between Taiwan and Japan — nations bounded by geography, shared democratic values and a complicated colonial legacy — has always been robust, despite being informal.
Today, that bond is more important than ever.
Taiwan views Japan with deep affinity, a sentiment shaped in part by the legacy of modernization during Japanese colonial rule. Politically, the relationship has sharpened amid rising Chinese aggression. Under former Japanese prime minister Shinzo Abe, Tokyo’s rhetoric shifted dramatically. Abe’s declaration that “a Taiwan emergency is a Japanese emergency” aligned Japan’s security with Taiwan’s stability. Japan’s 2022 National Defense Strategy identified Taiwan as a critical concern, and Tokyo has consistently supported Taipei’s participation in global forums, despite Beijing’s objections.
Why does Japan care so deeply? The answer lies in geography and economics. Taiwan is only 110km from Japan’s southwestern islands. Should conflict erupt, it would likely spill into Japanese territory or airspace. More crucially, Taiwan straddles vital sea lanes — the Taiwan and Luzon straits — through which nearly 80 percent of Japan’s energy imports pass. Any disruption to the maritime arteries could cripple Japan’s economy.
What is striking and troubling is that Japan appears at times more concerned about Taiwan’s security than many in Taiwan itself. While Japan runs TV programs and high-level dialogues on the risks of a Taiwan Strait conflict, some people remain disturbingly disengaged. Pro-China voices continue to operate freely within Taiwanese media and democratic institutions, while civic scrutiny of national security issues often gives way to apathy, partisanship or complacency.
The imbalance is untenable. Taiwan cannot outsource its survival. The burden of defending the nation’s democracy must rest with Taiwanese.
That begins with vigilance at home and abroad. The public must hold lawmakers and civil servants to account. They must challenge pro-China media narratives and reject candidates or institutions that undermine Taiwan’s sovereignty. Civic engagement, public pressure and democratic participation are national security imperatives.
“We have to prepare for war in order to avoid war,” Lai said in the interview.
He emphasized that the development of indigenous uncrewed weapons systems is purely defensive and proposed a cooperation with Japan in the uncrewed vehicle sector, signaling an opportunity for shared innovation and collective security.
Collaboration with Japan reflects a growing alignment between the two democracies. It is a partnership shaped by history, grounded in values and driven by necessity.
As authoritarian pressure intensifies across the Taiwan Strait, Taipei must not let its allies outpace its concern or commitment. Democracy cannot be defended by proxies. It must be protected by its own people.
On Sept. 3 in Tiananmen Square, the Chinese Communist Party (CCP) and the People’s Liberation Army (PLA) rolled out a parade of new weapons in PLA service that threaten Taiwan — some of that Taiwan is addressing with added and new military investments and some of which it cannot, having to rely on the initiative of allies like the United States. The CCP’s goal of replacing US leadership on the global stage was advanced by the military parade, but also by China hosting in Tianjin an August 31-Sept. 1 summit of the Shanghai Cooperation Organization (SCO), which since 2001 has specialized
In an article published by the Harvard Kennedy School, renowned historian of modern China Rana Mitter used a structured question-and-answer format to deepen the understanding of the relationship between Taiwan and China. Mitter highlights the differences between the repressive and authoritarian People’s Republic of China and the vibrant democracy that exists in Taiwan, saying that Taiwan and China “have had an interconnected relationship that has been both close and contentious at times.” However, his description of the history — before and after 1945 — contains significant flaws. First, he writes that “Taiwan was always broadly regarded by the imperial dynasties of
The Chinese Communist Party (CCP) will stop at nothing to weaken Taiwan’s sovereignty, going as far as to create complete falsehoods. That the People’s Republic of China (PRC) has never ruled Taiwan is an objective fact. To refute this, Beijing has tried to assert “jurisdiction” over Taiwan, pointing to its military exercises around the nation as “proof.” That is an outright lie: If the PRC had jurisdiction over Taiwan, it could simply have issued decrees. Instead, it needs to perform a show of force around the nation to demonstrate its fantasy. Its actions prove the exact opposite of its assertions. A
A large part of the discourse about Taiwan as a sovereign, independent nation has centered on conventions of international law and international agreements between outside powers — such as between the US, UK, Russia, the Republic of China (ROC) and Japan at the end of World War II, and between the US and the People’s Republic of China (PRC) since recognition of the PRC as the sole representative of China at the UN. Internationally, the narrative on the PRC and Taiwan has changed considerably since the days of the first term of former president Chen Shui-bian (陳水扁) of the Democratic
