The Indo-China Border Trade Union on Thursday submitted to Prime Minister Narendra Modi and sought his intervention through the office of the Deputy Commissioner, Kinnaur, Amit Kumar Sharma. The barter trade is a traditional system and not a commercial import-export transaction involving monetary payment. Under the Indo-China Border Trade Agreement, notified traders from border villages exchange specified goods directly without any monetary consideration. Sharma said the Indo-China Border Trade Union submitted a memorandum to the PM seeking his intervention through his office. The traders have urged the Union Government to exempt goods imported through Shipki La from IGST.
