"A city in eastern China's Jiangsu province plans to use the mainland's sovereign digital currency in cross-border trade with Belt and Road countries, as local governments warm up to the electronic money known as the e-CNY. Xuzhou, the starting point of many Europe-bound freight trains from China, has published a plan that promotes the e-CNY, including its usage in cross-border trade. The city has 18 regular cross-border railway lines to 21 countries in Europe and Asia."
