China has made important breakthroughs in polar regions and deep sea exploration in the past few years. In February, China opened its fourth Antarctic research base Taishan. In 2012, Jiaolong, the country's most advanced manned submersible, achieved a record dive depth of more than 7,000 meters in the Pacific's Mariana Trench.
