Some 52 percent of Americans said China was the "leading economic power in the world today," against 32 percent who said their own country, the Gallup poll said. The percentage who said China has soared over recent years. Seven percent identified Japan as the leading economic power, according to the poll, which surveyed 1,015 US adults this month. The poll was released as data showed that China became the world's second largest economy in 2010, dethroning Japan which held the title for 42 years. But at $5.879 trillion, China's GDP last year was still well below the $14.660 trillion in the United States, according to preliminary figures from the two countries. However, some economists believe that China -- which has four times the US population and, as a developing country, much faster growth -- will overtake the United States in the 2020s. Asked who would be the leading economic power in 20 years, 47 percent of Americans said China, with 35 percent saying their own country, the poll said. -- President Barack Obama defended his $3.7 trillion proposal for fiscal year 2012 on Monday, characterizing the plan as a successful balance of sorely needed new investments and long-term spending reductions necessary to reduce the federal debt.
