Pakistan, last week, banned two charities linked to Saeed.
According to a media report, the vast network of Islamist charities taken over by the Pakistani Government includes a horse-breeding stable, a fleet of trucks, a swimming academy, martial arts classes and thousands of staff and volunteers.
However, the sheer scale and diversity of the charities founded by Saeed will pose a huge challenge for Pakistan. It would be difficult for the government to run, track and control the funding and source of income of the banned charities.
"We're still collecting details about the Jamaat-ud-Dawa (JuD's) facilities which have been taken over. Our financial strategists are in consultation with the federal government to prepare a plan to run these facilities," a spokesman for the Punjab provincial government, Malik Mohammad Ahmad Khan said.
Islamabad hopes that by seizing control on JuD and Falah-e-Insaniat Foundation (FIF) charities, which the US has termed as terrorist fronts, it can avoid itself being included on a global watchlist of the country, that has been long criticised by others to be doing very little to curb militant financing and terrorism.
The LeT has been banned in Pakistan since 2002. But Saeed, who denies the involvement in the funding of militants and inciting religious violence, was freed by a Pakistani court from house arrest last year and his charity wings had been allowed to remain in operation.
Those charities are the focus of a motion co-sponsored by the US and European allies calling for Pakistan to be placed on the terrorist financing watchlist maintained by the Financial Action Task Force (FATF), a global money-laundering watchdog.
Pakistan was on the FATF "grey list" from 2012 to 2015. Islamabad is going all out to avert being put back on the list, a measure officials fear could hurt its economy, by taking a series of measures such as amending the country's anti-terrorism law and banning JuD and FIF from collecting charities from people.
