Germany and Japan Strengthen Defense Ties Amid China’s Rising Influence

Germany and Japan are stepping up their defense and security cooperation as concerns grow over China’s expanding power in the Indo-Pacific. Speaking during a visit to a Japanese naval base, German Foreign Minister Johann Wadephul emphasized that borders must not be shifted by force, pointing to regional tensions around Taiwan.
Germany continues to adhere to the “one China policy” but maintains economic and cultural ties with Taiwan, stressing that any reunification must be peaceful. Wadephul also underlined that systemic rivalry with Beijing is becoming increasingly central in international relations, and Germany intends to take on greater responsibility alongside Japan.
Japan, less dependent on Chinese supply chains than Germany, has been diversifying its access to rare earths and critical materials. German business leaders accompanying Wadephul noted the need to reduce reliance on China, learning from Japan’s stronger risk management strategies.
The partnership has been reinforced by shared positions on Ukraine, with Japan providing extensive aid while Germany accuses Beijing of supporting Russia. Both nations see stability in the Taiwan Strait as crucial to global security and trade. Recent years have also seen German warships and fighter jets take part in joint drills with Japanese forces, as both sides deepen military cooperation and explore closer defense industry collaboration.
