McDonald's Corp raised the prices of four products by 1 yuan ($0.15) in China at the end of April, the company confirmed on Tuesday.
The price increase is around 17 percent and, apart from saying it was for structural adjustment, McDonald's did not give a specific reason for the rise.
It was the company's second rise in China this year. The four products for breakfast and lunch were not included in previous rise.
The price of some McDonald's products went up by 0.5 to 2 yuan on Jan 12.
McDonald's explained in January that the price rise resulted from the continuous rise in costs of materials and other elements.
It is possible that other fast-food chains will follow the rise this year, business insiders said, because the cost of human resources, raw materials and transportation is still going up.
