According to the U.S.-based newspaper The World Journal, on the occasion of the 20th anniversary of Macao's return to China on December 20th, Macao, which has developed through gambling, has undergone earth-shaking changes. Macao has triumphed in its competition with Las Vegas, the gambling city in the United States. This special administrative region of China, which has less operating space and fewer tourists than the latter, has replaced it to become the world's largest gambling market.
