From promoting the full revitalization of Northeast China in the new era to promoting the rise of the central region in the new era, and from deepening the coordinated development of the Beijing-Tianjin-Hebei region to deepening the integrated development of the Yangtze River Delta... Since the 20th National Congress of the Communist Party of China, General Secretary Xi Jinping has successively chaired eight symposia, keeping in view the national "one chessboard," working tirelessly and advancing step by step, and making a series of major decisions and arrangements to promote the implementation of the regional development strategy.
