Core Viewpoint - The article discusses China's decision to strengthen export controls on dual-use items to Japan, citing national security and international obligations as the primary reasons for this action [2]. Group 1: Export Control Measures - The Chinese government has announced a ban on all dual-use items exported to military users in Japan, as well as any end-users that could enhance Japan's military capabilities [2]. - Violations of these regulations will lead to legal consequences for organizations and individuals transferring or providing dual-use items from China to Japan [2]. Group 2: Rare Earth Elements Impact - Reports indicate that China is considering tightening export license reviews for seven categories of medium and heavy rare earth elements, including samarium, gadolinium, terbium, dysprosium, lutetium, scandium, and yttrium, effective from April 4, 2025 [2]. - Japan's reliance on China for heavy rare earth elements, particularly those used in electric vehicle drive motors, is nearly 100%, which poses a significant risk to Japan's economy if exports are restricted [2]. - If China imposes a three-month restriction on rare earth exports to Japan, it could result in approximately 660 billion yen in losses, leading to a 0.11% decline in both nominal and real GDP [2]. - A one-year restriction could escalate losses to around 2.6 trillion yen, resulting in a 0.43% decrease in annual nominal and real GDP [2].
