On March 24, 2016, President Xi Jinping heard a report on the creation of Beijing's "subsidiary center" and another area where non-capital functions would be shifted from Beijing. Tongzhou and Xiong'an will form two "wings" for Beijing and create new growth engines for the Beijing-Tianjin-Hebei region. On May 27, 2016, Xiong'an New Area appeared for the first time in a report reviewed at a Political Bureau meeting of the Communist Party of China (CPC) Central Committee. Establishing Xiong'an New Area is a major historic and strategic choice made by the CPC Central Committee with Xi Jinping as the core. It is of national significance and a strategy crucial for a millennium to come, according to a circular issued by the CPC Central Committee and the State Council on April 1, 2017.
