Chinese Premier Wen Jiabao Thursday urged nation to work harder to develop technologies that are "more secure and reliable."

The nation should brace up to develop technological brands with China's own intellectual property rights and products with international competitiveness, Wen said at the site of a deadly weekend train collision.

He said that was "a lesson to be learned" from the accident that left 39 people dead and 192 others injured last Saturday.

Wen said he was "confident in the China's future, no matter in its development, construction, technology or education."
