ISLAMABAD, Pakistan — Pakistan said on Tuesday that it would take new steps to seize and freeze the assets of people and militant groups who are on the United Nations’ list of designated terrorists, after months of international criticism.

The announcement came as India and Pakistan were still on edge after a suicide bombing in Kashmir last month led to a military clash between the two. And last month, a financial watchdog group, the Paris-based Financial Action Task Force, said Pakistan was still not taking enough concrete steps to curb financing and money laundering by terrorist groups.

Pakistan risks being blacklisted by the task force, which would open the door to international sanctions that would be devastating to the country’s already teetering economy.

Pakistan’s military has long been accused by its neighbors and Western countries of cultivating militant groups to use as proxies, including the Afghan Taliban and Lashkar-e-Taiba, which was widely accused of orchestrating the 2008 Mumbai attacks that killed more than 160 people.
