WASHINGTON, United States (AFP) — The US, the world’s biggest donor, froze virtually all foreign aid on Friday, making exceptions only for emergency food, and military funding for Israel and Egypt.

Secretary of State Marco Rubio sent an internal memo days after President Donald Trump took office vowing an “America First” policy of tightly restricting assistance overseas.

“No new funds shall be obligated for new awards or extensions of existing awards until each proposed new award or extension has been reviewed and approved,” said the memo to staff seen by Agence France-Presse.

The sweeping order appears to affect everything from development assistance to military aid — including to Ukraine, which received billions of dollars in weapons under Trump’s predecessor Joe Biden as it tries to repel a Russian invasion.

The directive also means a pause of at least several months of US funding for PEPFAR, the anti-HIV/AIDS initiative that buys anti-retroviral drugs to treat the disease in developing countries, largely in Africa.

Launched under president George W. Bush in 2003, PEPFAR is credited with saving some 26 million lives and until recently enjoyed broad popular support along partisan lines in Washington.

But the memo explicitly made exceptions for military assistance to Israel — whose longstanding major arms packages from the United States have expanded further since the Gaza war — and Egypt, which has received generous US defense funding since it signed a peace treaty with Israel in 1979.

Rubio also made an exception for US contributions to emergency food assistance, which the US has been contributing following crises around the world including in Sudan and Syria.

Lawmakers from the rival Democratic Party said that more than 20 million people relied on medication through PEPFAR and 63 million people on US-funded anti-malaria efforts including nets.
