The first meeting to finalise the modalities for the corridor took place on the Indian side of the Attari-Wagah border on March 14.
Technical experts of the two countries met on March 19 during which alignment, coordinates and several other engineering aspects of the proposed corridor were discussed.
However, on March 29, India conveyed its strong concerns to Pakistan over the presence of a leading Khalistani separatist in a committee appointed by Islamabad on the Kartarpur project.
India had also postponed a previously-agreed meeting on the project, which was to be held on April 2 in Wagah, on the Pakistani side. On May 27, Indian officials held a meeting to discuss the modalities for the project.
