The Vatican's financial revenue mainly depends on tourism, opening banks, issuing stamps, renting real estate, bank interest on special property funds, papal tributes, Christian donations and so on. There are tens of billions of dollars of investment in many countries in North America and Europe, and its capital has penetrated into many economic sectors in Italy, especially the bank credit and real estate system. Real estate alone has reached more than 460,000 hectares, and gold and foreign exchange reserves have reached more than 654.38+0 billion US dollars. After the mid-1970s, faced with the increasingly serious financial difficulties, the fiscal deficit continued year after year.

The Vatican has no diplomatic relations with China. After the founding of People's Republic of China (PRC), the Vatican adopted a hostile policy and seriously interfered in China's internal affairs. The vast number of patriotic clergy and Christians in China organized themselves to sever ties with the Holy See and implement the policy of running their own churches independently. At present, the foreign exchange reserves of gold alone have reached more than $654.38+000 billion, and the annual fiscal revenue is nearly $200 million. There is no doubt that the Vatican should be the country with the highest per capita income in the world and the richest country in the world at present.
