The Communist Party government in China should closely monitor the country's wealth gap and focus on poverty relief, experts said, as China has the most new entries on Forbes magazine's annual ranking of the world's billionaires in 2016.
The magazine published the ranking on Monday which had 196 new billionaires, of which 76 were from the Chinese mainland and 25 from the US.
While the US has the single largest number of billionaires at 565, China followed with 319.
However, China's Gini coefficient, an inequality index where zero equals perfect equality, stood at 0.465 last year - higher that the 0.462 in 2015, said Ning Jizhe, head of the National Bureau of Statistics.

According to a report in the state-run Xinhua news agency, Ning attributed the higher index to slower pension growth for some urban groups and the negative effect of falling grain prices on farmers' income.
"The Gini coefficient shows that China continues to suffer from a relatively high level of income disparity," said Wang Junhui, a research fellow at Chengdu-based Survey and Research Center for China Household Finance of Southwestern University of Finance and Economics.
Li Chang'an, a professor at Beijing's University of International Business and Economics, said it was crucial to address poverty relief, if China is to reduce the wealth gap.
China should create more jobs and raise incomes, as many Chinese categorised as poor were unemployed, Li said.
A government work report this year says 12.4 million people in rural areas had been freed from poverty in 2016.
