CNY is the ISO 42 17 currency code of RMB, which stands for the abbreviation of China dollar or RMB. Renminbi is the legal tender of China and is issued by the Central Bank of China. CNY is a universal identifier used in global transactions, which is mainly used for exchange rate conversion and foreign exchange transaction calculation.

With the acceleration of RMB internationalization, more and more countries and regions begin to use CNY as the transaction currency. CNY exchange rate has become one of the most concerned market indicators in the world, affecting global commodity prices and global capital flows. As a representative of China's emerging economies, CNY's international status has been continuously improved, which shows China's increasingly important position in the global economic structure.

At the same time, the internationalization of CNY has also promoted the opening of China's financial market and attracted more foreign investors to invest in the China market. More and more China companies are also issuing RMB bonds overseas, which further promotes the internationalization of RMB.

It has become a trend to use CNY as the transaction currency. The internationalization of CNY will continue to promote the integration of China and the world economy, and China will gradually play a leading role in the global economy.
