Chinese ethnic group biggest earners in the UK and Indians are in the second rank.
Chinese and Indian ethnic group workers have higher average earnings than their white British counterparts.
But the data showed all other ethnic groups have lower wages than white British workers. The Office for National Statistics said employees in the Bangladeshi ethnic group have the largest pay gap, earning 20% less than white British employees. On average, ethnic minorities earn 3.8% less than white ethnic groups.
In 2018, employees from the Chinese ethnic group earned 30.9% more than white British employees.
Hugh Stickland, senior ONS analyst, said: "Overall, employees from certain ethnic groups such as Indian and Chinese, have higher average earnings than their white British counterparts."However, all other ethnic groups have average wages lower than for white British employees, with employees from the Bangladeshi ethnic group having the largest pay gap.
"However, once characteristics such as education and occupation are taken into account, the pay gap between white British and most other ethnic groups becomes narrower, though significant differences still remain."
Bangladeshis are the UK's lowest earners
The data - based on median gross hourly earnings between 2012 and 2018 - shows that the Chinese ethnicity group is the highest paid, receiving £15.75 an hour in 2018.
That group is followed by the Indian ethic group - which earns £13.47 an hour - and mixed/multiple ethnicity group, with a £12.33 hourly pay rate.
The median pay of the white British group was £12.03. The Bangladeshi group had the lowest median hourly pay of £9.60 with the second-lowest paid group being of Pakistani origin at £10 an hour.
The data comes after a found black and ethnic minority workers were paid significantly less than their white counterparts.
"The harsh reality is that even today race still plays a real role in determining pay," said Frances O'Grady, general secretary of the TUC.
"Ministers must take bold action to confront inequality and racism in the labour market. The obvious first step is to introduce mandatory ethnicity pay gap reporting without delay," she said.
The government has consulted on whether mandatory reporting will help address disparities between the pay and career prospects of minorities.
When taking other factors into account, such as education, UK-born employees in the Indian and Chinese ethnic groups do not have pay gaps that are "statistically different" from the UK-born white British employees, the ONS found.
