Sanctions against Russia are not achieving their intended purpose as Russia acquires what it needs through various means, including seeking out dual-use technology. Enforcing these sanctions is complicated due to Russia using less advanced systems, seeking civilian technology, and challenging international supply chain tracking. Additionally, China's significant manufacturing capacity poses a challenge as it supplies Ukrainian arms development, albeit to a lesser extent than Russia. Enforcing sanctions against Chinese companies could potentially impact Ukrainian military procurement. These complexities highlight the challenges in enforcing sanctions against Russia and China, given their strategies for technology acquisition.
