Peoples Republic of China
The People's Republic of China (PRC), is the most populous country in the world, with over 1.339 billion citizens. Located in East Asia, the country covers approximately 9.6 million square kilometers (3.7 million square miles). It is the world's second-largest country by land area, and the third- or fourth-largest in total area, depending on the definition of total area.
With its booming economy and vast population, the 'repatriation' of stamps back to China is stimulating a strong demand for all stamps of the PRC and causing a substantial rise in catalog prices for the stamps of PRC.
