BEIJING, Sept. 17 (Xinhua) -- Chinese President Hu Jintao's speech on the 30th anniversary of the founding of the Shenzhen special economic zone (SEZ) was published in five ethnic minority languages on Friday.

Shenzhen, a southern coastal city neighboring Hong Kong, marked its 30th anniversary as China's first economic reform zone on Sept. 6.

At that day's celebratory rally, Hu said the central government would always support the country's special economic zones, embarking on "brave exploration" in their roles as "first movers."

"The SEZs will not only continue, but should work better," Hu said.

The late Chinese leader Deng Xiaoping first proposed building Shenzhen into a SEZ in the late 1970s.

On Aug. 26, 1980, China's top legislature approved the establishment of the Shenzhen SEZ.

The speech was published by the Ethnic Publishing House in five minority languages, including Mongolian, Tibetan, Uygur, Kazakstan and Korean.
