Read the passage and answer the questions that follow. Unsurprisingly, the latest conviction comes a month after the FATF, a global dirty money watchdog, urged Pakistan to complete an internationally agreed action plan to fight terror financing. In February 2018, Pakistan endorsed a UN list of terrorist organizations operating in the country and enforced a nationwide ban on them, including the LeT and the JuD, just before a meeting of the FATF. But the FATF still placed Pakistan on its “grey list” in June 2018, and demanded more actions from Islamabad to avoid being blacklisted, which could invite economic sanctions. Ever since, Pakistan, which cannot afford to be blacklisted, especially when its economy is in shambles, has moved against Saeed. The Anti-Terrorism Department’s FIRs against Saeed and his aides accuse the JuD of financing terrorism from its fund collections in the name of charity through NGOs. While the authorities’ move against Saeed is welcome, the question is whether these are genuine attempts to fight terrorism or half-hearted measures to dodge international pressure. There are doubts because Pakistan had used anti-India and anti-Afghan terrorist networks for strategic advantages. It was this dual policy of fighting terror at home while nurturing terror groups that target its rivals abroad that has been responsible for Pakistan’s predicament. If it is serious about fighting terrorism, Pakistan should crackdown on terror financing and terror infrastructure. The international community and organizations, including the FATF, should keep up the pressure until Islamabad shows tangible outcomes. According to the passage, why FATF did not remove Pakistan from the "grey list"?
