US fast food giant McDonald's raised prices of certain products in China from July 13, the Beijing Times reported Monday.

The price hike is the fourth since July 2010, the paper said.

McDonald's told the paper that the price hike was a "structural adjustment", in line with the company's overall strategy.

The price of Chicken McNuggets (5 pieces) was raised to 8 yuan ($1.19) from the previous 6 yuan, spicy McWings was raised to 9 yuan from 7 yuan, and a milkshake now costs 12 yuan instead of 9.5 yuan.

It also raised the price of hamburgers, french fries, chicken wings, and most combos, excluding Chicken McNugget combos. The price hikes were between 0.5 yuan to 2 yuan, the paper said.

KFC, another US fast food provider, said it currently has no plan to adjust product prices, according to the paper.
