The Lingang expansion of the Shanghai free trade zone (FTZ) was officially unveiled on Tuesday.

As a major strategic decision made by the Communist Party of China Central Committee to further opening up, the addition of the Lingang area demonstrates China's clear stand to adhere to all-round opening up in the new era and an important measure taken to actively lead the healthy development of economic globalization, officials said.
