The Karasu Port of Entry at the Kulma Pass () is the only modern day border crossing between China and Tajikistan. Historically, two passes further south along the border, Nezatash Pass and Beyik Pass, have also been traversed. Northwest of Kulma Pass is the Uzbel/Kyzyl-Dzhiik Pass (also known as Uzbel Shankou, Pereval Kyzyl-Dzhiik, Wuzibieli Pass (), Kizil Jik Dawan, Kizöl-jiik Pass, K'o-tse-lo-chi-k'o Shan-k'ou, Qizil Jik Dāwan, Utzupieli Pass and Wu-tzu-pieh-li Shan-k'ou).
