Other problems involve states being reluctant to relinquish involvement in other regional groups, e.g., Tanzania's withdrawal from COMESA but staying within the SADC bloc for the Economic Partnership Agreement negotiations with the European Union. Many Tanzanians are also concerned because creating a common market means removing obstacles to the free movement of labour and capital. Free movement of labour may be perceived as highly desirable in Uganda and Kenya, and have important developmental benefits in Tanzania; however, in Tanzania there is widespread resistance to the idea of ceding land rights to foreigners, including citizens of Kenya and Uganda.
