China's 4G technology set international standards on Jan 18, 2012

On Jan 18, 2012, the fourth-generation mobile communication technology TD-LTE-Advanced was confirmed as one of the two international standards of the fourth-generation mobile communication (4G) by the International Telecommunication Union (ITU).

Primarily developed by China, the technology was owned by China Information and Communication Technologies Group Corporation.

It was proof that China ranked at the leading place in the field of mobile communication standards in the world.

It was also a milestone of the country's mobile communication standard industry. Since then, mobile communication in China has risen to international competitive levels.

First China-made TBM to dig across the Yellow River rolls off the production line on Jan 18, 2018

The first China-developed large-diameter slurry-balanced tunnel boring machine (TBM) rolled off the production line on Jan 18, 2018.

The machine, with complete proprietary intellectual property rights, was used for the heating pipeline project going through the Yellow River and was jointly developed by China Railway Construction Corporation Limited and China Huadian Corporation Ltd.

With an excavation diameter of 9.05 meters, the 132-meter long machine weighs about 1,500 tons and has an installed capacity of 3,500 kW.

It took only two months to design, assemble materials and manufacture the machine.
