The visit is taking place amid increasing pressure on Pakistan from the US and India with respect to the alleged inadequate implementation of the sanctions on Jamat-ud-Dawa chief Hafiz Saeed and entities linked to him.
However, Pakistani officials, insist that the trip is a routine visit.
State Department spokesperson Heather Nauert had at a briefing on Friday said that the US had clearly conveyed its concerns to Pakistan on Hafiz Saeed and called for his prosecution "to the fullest extent of the law". She had recalled that Saeed's name was on the UN list of designated terrorists.
The US reaction had come after Prime Minister Shahid Khaqan Abbasi said in a television interview that, "there is no case against Hafiz Saeed sahib in Pakistan. If there was a case, action would be taken. This is an issue that comes to the fore repeatedly but there is no truth in it".
The terms of reference of the monitoring team for Pakistan visit are not publicly known, but as per its general mandate it assists the 1267 Committee in keeping an eye on the freezing of the financial assets of listed persons and entities and checking provision of training and other material to them and their travel.
A Pakistani official gave a positive spin to the trip saying it would give an opportunity to share the steps taken by the government to implement the sanctions regime.
Pakistan has remained under the Financial Action Task Force (FATF) scanner over allegations by the US and India about the UNSC sanctions not being fully implemented.
