By introducing and extending the G′/G-expansion method, the new exact general solutions are constructed for 2+1-dimensional asymmetrical Nizhnik-Novikov-Veselov system. These solutions include general hyperbolic function solutions, general trigonometric function solutions and general rational function solutions. The solitary ware solutions are obtained when the constants involved in the general hyperbolic solutions are set at special values.
