No, you cannot use American dollars (USD) for everyday transactions in China in 2026. While some high-end hotels or international "friendship stores" might accept them as a courtesy, the exchange rate will be poor, and almost all shops, restaurants, and taxis will only accept the Renminbi (RMB/Yuan). In fact, China is now a nearly cashless society, where over 90% of transactions occur via Alipay or WeChat Pay. In 2026, it is a peer-to-peer essential to download these apps and link your international credit card before you arrive. Physical cash is still legally accepted but can be difficult to use as many vendors "don't have change." It is also important to note that as of January 2026, China has implemented stricter foreign exchange controls; if you need to exchange physical USD for Yuan at a bank, you will need your passport and should expect a lengthy administrative process. Your best strategy is to rely on digital payments or withdraw local currency from a "Bank of China" ATM upon landing.
