China's automobile import growth slowed in the first quarter, but the segment is expected to maintain reasonable growth in the next few years.

Customs statistics show that in the first three months of the year, China imported 284,000 vehicles, 21.7 percent more than in the same period last year.

"It's a normal and healthy rate," said Wang Yanxue, an auto analyst with Huachuang Securities. He predicted 20 percent growth in vehicle imports for the whole year and 1 million plate registrations.

"The growth will be twice the number of locally produced passenger vehicles," said Wang.

"The upgrading of China's automobile market and the stable economic environment mean that imports will continue to enjoy reasonable and rational growth over the next few years."

According to the China Association of Automobile Manufacturers, China's vehicle import sector maintained an average year-on-year growth rate of more than 30 percent over the past decade.

In 2011, the total sales of imported automobiles reached 1.04 million. Of those, 1.01 million were of passenger vehicles, up almost 30 percent year-on-year, 26 percentage points higher than the growth of total domestic vehicle sales. License plate registration of imported vehicles jumped 29 percent year-on-year to 830,000 units.
