What does the integration of Wuchang mean?

From June 5438 to February 2004, the Party Committee of Xinjiang Uygur Autonomous Region made a decision to let two "economic giants", Urumqi, the capital of Xinjiang, and Changji Hui Autonomous Prefecture, jointly implement the strategy of "economic integration of Wuchang", and set up the Wuchang Party Committee higher than the Party committees of the two places without involving the adjustment of administrative divisions of the two places, so as to speed up the pace of regional coordinated development.
