In a series of papers by Campana, H枚ring and Peternell, the authors established the K_X-MMP for terminal K盲hler threefolds. They also proved the abundance conjecture in this settings. This is a remarkable achievement by the authors despite the fact that some of fundamental tools of MMP for algebraic varieties, such as, Mori鈥檚 Bend and Break, Base point free theorem etc. do not hold for K盲hler manifolds. In this talk I will explain how to extend their K_X-abundance theorem to log canonical pairs (X, B), where X is a K盲hler threefold and K_X+B is nef.
