Since initiating economic reforms in 1979, China has transitioned from a stagnant economy to the fastest-growing major economy, doubling its GDP every eight years and lifting 800 million people out of poverty. With its economy becoming the largest based on purchasing power parity, China has established itself as a critical commercial partner for the U.S., though growth has slowed and faces challenges such as rising tariffs and trade tensions. The Chinese government has prioritized innovation to avoid the 'middle-income trap' but faces concerns over its industrial policies and intellectual property practices, affecting U.S.-China relations.
