The situations of Eastern region of D.R.Congo fell into turbulence. There are two conflicts producing an effect on the situations of Eastern D.R.Congo，which includes Ituri Conflict and “M23” rebellion. Ituri conflict is mainly caused by two ethnic groups，fighting for land，sources，and local power. The influence of Ituri conflict is limited in the Ituri province，and didn’t lead turbulence to the whole Eastern D.R.Congo，which got less attention than “M23” rebellion. The turbulence of Eastern D.R.Congo is mainly caused by the revitalization of “M23” rebels. The paper argues，as a result of Eastern D.R.Congo turning into the battlefield of proxy war of the Great Lakes conflict，the revitalization of “M23” should be explained in the context of the Great Lakes conflict. The revitalization of “M23” is the chain reaction caused by Uganda-D.R.Congo military cooperation against the Allied Democratic Forces（ADF）in November 2021.To some degree，the Eastern D.R.Congo conflict reflects the collision among the conflicting states of the Great Lakes region. Hence，without the solution of the conflict of the Great Lakes，the Eastern D.R.Congo conflict will not end in the short and medium term.
