The election of Sanae Takaichi as Japan's first female prime minister on Tuesday holds significant implications not only for the social and economic development of the nation itself but also for regional stability and prosperity.

China and Japan, as close neighbors and influential players in Asia and the world, share a relationship that extends beyond bilateral concerns.

When Takaichi takes office, the principles outlined in the four important political documents between China and Japan — the 1972 Joint Communique, the 1978 Treaty of Peace and Friendship, the 1998 Joint Declaration, and the 2008 Joint Statement — should serve as crucial guides for her handling of bilateral relations. These four documents lay the political and legal foundation for developing a stable and mutually beneficial relationship.

Given Japan's wartime history, it is essential that the Japanese leader appreciate the sensitivity surrounding Japan's militarization. It is important to uphold the spirit of Japan's pacifist Constitution rather than seeking to expand the country's military capabilities, which could harm relations with neighboring countries. Japan must also faithfully honor its political commitments on historical issues. Taking history as a mirror it should look toward the future and keep the big picture in mind. It should avoid any actions that damage mutual trust.

On the Taiwan question, Japan must strictly abide by the principles of the four political documents and its own commitments, refrain from interfering in China's internal affairs, and handle all relevant issues prudently. Japan should also act cautiously on matters concerning the South China Sea and East China Sea, which touch upon China's core interests.

Takaichi should be mindful that the trade war initiated by the US targets not just China but also Japan and a large number of countries worldwide. It won't serve its own interests for Japan to ingratiate itself with Washington. Japan needs to have an independent stance rather than serving as a pawn in others' geopolitical games.

China's development presents opportunities not only for the world but particularly for its neighbors, including Japan. Frictions between the two countries have frayed bilateral ties over the past more than a decade. It is important the two sides work together to manage their differences.

China's position on its relations with Japan has been consistent and clear — it hopes Japan will move in the same direction as China and work to maintain the political foundation of bilateral ties.

Economic interdependence between China and Japan is a critical aspect of their relationship. The two countries have deeply intertwined economic interests and supply chains, which necessitate a commitment to cooperation and mutual benefit.

As Takaichi takes office, it is crucial that she resist any pressure to pursue economic "decoupling" and instead focus on enhancing economic exchanges, promoting trade and ensuring the stability of supply chains. Such cooperation will be beneficial not only for China and Japan but also for the broader international community.

Strengthening cultural and people-to-people exchanges, particularly among the younger generation, would help foster mutual understanding and trust and create a foundation for long-term friendship and cooperation.

It is hoped that under Takaichi's leadership, Japan will work with China in the same direction, strictly observe the principles of the four political documents, and uphold its commitments on major issues such as history and Taiwan. By engaging in candid dialogue and fostering mutual understanding, Japan should advance mutually beneficial ties with China and pave the way for a future characterized by stability and cooperation.
