Most recently, both BABAR and Belle experiments found evidences of neutral D mixing. In this paper, we discuss the constraints on the strong phase difference in D{sup 0}{yields}K{pi} decay from the measurements of the mixing parameters, y{sup '}, y{sub CP}, and x at the B factories. With CP tag technique at {psi}(3770) peak, the extraction of the strong phase difference at BES-III is discussed. The sensitivity of the measurement of the mixing parameter y is estimated in BES-III experiment at {psi}(3770) peak. Finally, we also make an estimate on the measurements of the mixing rate R{sub M}.
