Title: Economy of China
Content:  The renminbi ("people's currency") is the currency of China, denominated as the yuan, subdivided into 10jiao or 100fen. The renminbi is issued by the People's Bank of China, the monetary authority of China. The ISO 4217 abbreviation is CNY, although also commonly abbreviated as "RMB". As of 2005, the yuan was generally considered by outside observers to be undervalued by about 30–40%. However, in 2017, the IMF stated that the yuan was correctly valued. The renminbi is held in a floating exchange-rate system managed primarily against the US dollar. On 21 July 2005, China revalued its currency by 2.1% against the US dollar and, since then has moved to an exchange rate system that references a basket of currencies and has allowed the renminbi

Title: History of Chinese currency
Content:   The history of Chinese currency spans more than 3000 years. Currency of some type has been used in China since the Neolithic age which can be traced back to between 3000 and 4500 years ago. Cowry shells are believed to have been the earliest form of currency used in Central China, and were used during the Neolithic period. Around 210 BC, the first emperor of China Qin Shi Huang (260–210 BC) abolished all other forms of local currency and introduced a uniform copper coin. Paper money was invented in China in the 9th century, but the base unit of currency remained the copper coin. Copper coins were used as the chief denomination of currency in China until the introduction of the yuan in the late 19th century by the Republic of China. Currently, the renminbi is the official currency of the People's Republic of China (PRC). It is the legal tender in mainland China, but not in Hong Kong or Macau. The special administrative regions of Hong Kong and Macau use the Hong Kong dollar and the Macanese pataca, respectively. In the Republic of China (ROC), the New Taiwan dollar is the official legal tender in Taiwan since 2000.

Title: Yuan (currency)
Content:  Today, the term "Yuan" usually refers to the primary unit of account of the renminbi (RMB), the currency of the People's Republic of China. RMB banknotes start at one Yuan and go up to 100 Yuan. It is also used as a synonym of that currency, especially in international contexts – the ISO 4217 standard code for renminbi is CNY, an abbreviation of "Chinese yuan". (A similar case is the use of the terms sterling to designate British currency and pound for the unit of account.) The symbol for the yuan (元) is also used in Chinese to refer to the currency units of Japan (yen) and Korea (won), and is used to translate the currency unit dollar as well as some other currencies; for example, the United States dollar is called Meiyuan in Chinese, and the euro is called Ouyuan. When used in English in the context of the modern foreign exchange market, the Chinese yuan (CNY) refers to the renminbi (RMB), which is the official currency used in mainland China.
Title: Foreign-exchange reserves of China
Content:   The foreign exchange reserves of China are the state of foreign exchange reserves held by the People's Republic of China, comprising cash, bank deposits, bonds, and other financial assets denominated in currencies other than China's national currency (the renminbi). In July 2020, China's foreign exchange reserves totaled US$3.15 trillion, which is the highest foreign exchange reserves of any country. The management of foreign exchange reserves is governed by the State Administration of Foreign Exchange (SAFE) and the People's Bank of China. The composition of foreign exchange reserves is a state secret in China. The United States has designated China a currency manipulator under the 1988 Omnibus Foreign Trade and Competitiveness Act, as engaging in “unfair currency practices” that gives it a trade advantage. In August 2019, the Trump administration, as part of the China–United States trade war, redesignated China as a currency manipulator. That designation was removed in January 2020.
Title: Economic history of China (1912–1949)
Content:  The currency of China was initially silver-backed, but the nationalist government seized control of private banks in the notorious banking coup of 1935 and replaced the currency with the Fabi, a fiat currency issued by the ROC. Particular effort was made by the ROC government to instill this currency as the monopoly currency of China, stamping out earlier Silver and gold-backed notes that had made up China's currency. Unfortunately, the ROC government used this privilege to issue currency en masse; a total of 1.4 billion Chinese yuan was issued in 1936, but by the end of the second Sino-Japanese war some 1.031 trillion in notes had been issued. This trend worsened with the resumption of the Chinese Civil war in 1946. By 1947, some 33.2 trillion of currency was issued. This was done in large part as an attempt to close the massive budget deficits brought about by the war (taxation revenue was just 0.25 billion, compared with 2500 billion in war expenses). By 1949, the total currency in circulation was 120 billion times more than in 1936.

That achieved, a revaluation occurred in 1955 at the rate of 1 new yuan = 10,000 old yuan. As the Communist Party of China took control of ever larger territories in the latter part of the Chinese Civil War, its People's Bank of China began to issue a unified currency in 1948 for use in Communist-controlled territories. Also denominated in yuan, this currency was identified by different names, including "People's Bank of China banknotes" (from November 1948), "New Currency" (from December 1948), "People's Bank of China notes" (from January 1949), "People's Notes" (人民券, as an abbreviation of the last name), and finally "People's Currency", or "renminbi", from June 1949.
Title: Renminbi
Content:   The various currencies called yuan or dollar issued in China as well as Taiwan, Hong Kong and Macau were all derived from the Spanish American silver dollar which China imported in large quantities from Spanish America from the 16th to 20th centuries. The first locally minted silver dollar or yuan accepted all over Qing Dynasty China (1644-1912) was the silver dragon dollar introduced in 1889. Various banknotes denominated in dollars or yuan were also introduced, which were convertible to silver dollars until 1935 when the silver standard was suspended and the Chinese yuan was made fabi (legal tender currency). The renminbi was introduced by the People's Bank of China in December 1948, about a year before the establishment of the People's Republic of China. It was issued only in paper form at first, and replaced the various currencies circulating in the
