It addresses the current challenges that prevent such inclusiveness and suggests future trends of its development to be of benefit to the wider city community. It explains how spaces in divided cities are carved up into perceived ownerships and territorialized areas, which increases tension on the shared space between territories; the control of which can often lead to inter-community disputes. The paper reports that common shared space in-between conflicting communities takes on increased importance since the nature of the conflict places emphasis on communities＇ confidence, politically and socially, while also highlighting the necessity for confidence in inclusion and feeling secure in the public domain. In order to achieve sustainable environments, strategies to promote shared spaces require further focus on the significance of everyday dynamics as essential aspects for future integration and conflict resolution.展开更多

Economically, a community will integrate regional economies and share great interests for common prosperity. Politically, a community will stabilize the region with trust and cooperation. In terms of security, a community will realize the lasting peace of the region. The three economies of China, Japan, and the ROK account for a vast majority of Northeast Asia＇s regional economy. China and the ROK are two key players in the Northeast Asian community building. China-ROK cooperation will be helpful for China-Japan relations that now appear to be in a difficult situation. Northeast Asian economic cooperation has developed into a multi-layered structure both in institutional and non-institutional ways. In order to build the Northeast Asian community, those three countries must first improve and make three close bilateral relationships. However, Northeast Asian community building should not just include China, Japan, and the ROK. The DPRK, Mongolia, and also Russia should be engaged as early as possible. Northeast Asian community is a vision and also a dream that needs great efforts to be realized by both a good spirit and real actions.展开更多
