China's information technology market is projected to increase a middling 10 percent this year with the smartphone and tablet sector leading the growth, research company IDC said on Tuesday.

The nation's slowing economy and mounting concerns over Sino-United States cybersecurity conflicts are likely to drive away some overseas tech companies and thus lower overall IT spending.

Assuming the economy remains stable, pent-up demand will drive IT spending growth back up to double digits before another likely slowdown occurs in 2015, analysts said.
