While a command economy might not be a perfect system, communist countries have learned to adapt to a mainly capitalist global market. China has the second-largest economy in the world, with a GDP of 13.4 trillion U.S. dollars. China is technically closer to an authoritarian capitalist system and relies on a socialist market. While keeping substantial government control on the economy, China allows for a private sector worth over 50% of its GDP. For 40 years, China has had the highest economic growth rate in the world. This is because they have created a system that not only survives but thrives amidst a capitalist global economy.
Vietnam is another example of financial success, with the fastest growing economy in the world. After the war, the country went through aggressive reconstruction. They were able to rapidly gain control of the small businesses, farms, and factories without any resistance because of its victory in the war. Vietnam's economy was built before the 1991 fall of the Soviet Union's, meaning that they could get support during the most challenging parts of reconstruction. The country quickly opened itself up to the global market, encouraging trade, and becoming prominent in the export business. Vietnam has stayed close to a communist economy's central idea but has adopted socialist practices when dealing in international trade. Its vast agricultural and industrial power has made its economy extremely successful. Despite the anti-American sentiment after the war, Vietnam recognized the U.S.'s value as a trade partner and took steps to lift the U.S. embargo on trade. International investment and global trade rely on compromise, especially for communist countries. Communism is the minority in this world, and success isn't easy. When dealing with headstrong capitalists and influential socialists, Vietnam and China chose to adapt and compromise for their countries' good.
