We explore the possible enhancement of direct CP violating parameter epsilon'/epsilon in the general left-right model based on the SU(2)_L times SU(2)_R times U(1) gauge group. The mixing matrix of right-handed quarks, V_{CKM}^R is observable in the left-right model, and provides new source of CP violating phase. We calculate the parameter epsilon'/epsilon in the left-right model and show that the new phases from V_{CKM}^R can yield the sizable contribution to the direct CP violation enough to satisfy the recent measurements of Re(epsilon'/epsilon) from Fermilab KTeV and CERN NA48 experiments.
