NEW DELHI: The government will take a decision on a defence foundational agreement with the US on Wednesday after the cabinet committee on security (CCS) takes a look at the negotiated text. Top sources said the government was currently "taking stock" of the negotiations. The two sides have completed the agreed text of the India-specific Communications Compatibility and Security Agreement ( COMCASA ).If cleared by CCS, the pact is expected to be signed by defence minister Nirmala Sitharaman and her US counterpart, Jim Mattis after the dialogue on Thursday, and be the biggest deliverable of the inaugural dialogue.In 2007, Indian and US officials had negotiated a text for the same communications agreement but it was held back by the CCS then. Officials are therefore crossing their fingers this time, as they wait for political approval.The one-day dialogue will showcase the fastest growth in defence and security relations between India and US, outstripping other areas of engagement. India will place a liaison officer at the US' Navy Centcom in Bahrain, the first such outward posting. The defence minister and her US counterpart will finally set up a hotline, something that has been in the works for a while, though a previous plan for a hotline between the foreign minister and secretary of state has had to be shelved.India and the US are waiting to clear the Comcasa before working on the third foundational agreement, BECA (Basic Exchange and Cooperation Agreement for Geo-spatial Cooperation) also hanging fire for years.
