The export growth of China's electronic products slowed markedly last year to 11.9 percent, the Ministry of Industry and Information Technology (MIIT) announced Monday.

The total export value last year reached 661.2 billion U.S. dollars, up 11.9 percent year-on-year. However, the growth rate was 17.4 percentage points lower than that of the previous year, the MIIT data showed.

The export value of electronic products accounted for nearly 35 percent of the nation's total export value in 2011, according to the data. Computers and cell phones were the top two categories of exported electronic products.

In 2011, computer and mobile phone exports increased by 11.1 percent and 34.3 percent, respectively, to 105.88 billion U.S. dollars and 62.76 billion U.S. dollars, the data showed.

Meanwhile, the MIIT also announced that the country's imports of electronic devices hit a new high of 468 billion U.S. dollars last year, up 11 percent year-on-year. However, the growth rate saw a sharp decrease of 23 percentage points in comparison with that of 2010.
