Japan Protests China's Disrespectful Address of PM Takaichi

Tokyo filed a formal complaint with Beijing this week over what it characterized as a breach of diplomatic protocol: a Chinese Foreign Ministry spokesman had referred to Prime Minister Sanae Takaichi by her name alone, stripping away the title that convention demands when addressing a sitting head of government. The incident occurred on September 30, when spokesman Guo Jiakun discussed Japan's nuclear weapons and submarine discussions at a Beijing news conference. It might have passed unnoticed in ordinary times, but Japan and China are not in ordinary times.

On October 7, Japanese Foreign Ministry spokesman Toshihiro Kitamura made the complaint public, framing it not as a personal slight but as a matter of international custom. "Even when there are differences in our positions, I believe that, as a matter of international protocol, it is only natural to show appropriate respect to the leader of another country," Kitamura said at a regular briefing. He added that Tokyo was conveying this position to China through appropriate channels. The language was measured, almost apologetic in its restraint, but the message was unmistakable: Beijing had stepped over a line.

The timing of the complaint reflects how fragile the relationship between these two major powers has become. Relations have deteriorated sharply since 2025, when Takaichi suggested that Japan might intervene militarily if Taiwan faced attack from China. That statement struck at the heart of Beijing's most sensitive claim—that Taiwan is Chinese territory and that no foreign power should interfere in what it regards as an internal matter. For Japan to raise the possibility of military involvement was, from China's perspective, a direct challenge to its sovereignty and its strategic interests in the region.

The nuclear weapons discussion that prompted Guo's remarks added another layer of tension. Japan's exploration of nuclear capabilities and submarine technology has long concerned Beijing, which sees any Japanese military expansion as a potential threat. When Guo discussed this at his news conference, his choice to omit Takaichi's title may have been deliberate—a small gesture of disrespect that signaled China's displeasure with Japanese policy. Or it may have been careless. Either way, Japan decided it could not let the moment pass without response.

Yet even as Tokyo lodged its complaint, both nations appeared to be searching for a way back from the brink. Japanese lawmakers have been traveling to China in recent weeks in what observers interpret as a deliberate effort to ease tensions. Takaichi herself has struck a conciliatory note, calling China an "important neighbour" in a recent policy address and pledging to work toward a stable relationship between the two countries. These gestures suggest that neither side wants the relationship to spiral into open hostility, despite the genuine disagreements that divide them on Taiwan, nuclear policy, and regional security.

The complaint over protocol may seem trivial—a matter of titles and formalities in a world of weightier concerns. But in diplomacy, such details carry meaning. They signal respect or its absence, and they establish whether a relationship is conducted between equals or between a power and a lesser state. By insisting on the proper form of address, Japan was asserting its standing as a major nation whose leader deserves the courtesy due to any head of government. Whether Beijing will adjust its approach in future remains to be seen, but the complaint itself marks a moment when even the smallest gestures have become freighted with consequence.
