President Joe Biden has ordered the review of the Afghan peace agreement, which the U.S. and Taliban signed last year, to evaluate whether the Taliban are living up to their side of the agreement.

Jake Sullivan, the national security adviser for the Biden administration, spoke with his Afghan counterpart, Hamdullah Mohib, the White House said in a January 22 statement.

The U.S. is set to review the peace agreement reached under former President Donald Trump’s administration a year ago, “including to assess whether the Taliban was living up to its commitments to cut ties with terrorist groups, to reduce violence in Afghanistan, and to engage in meaningful negotiations with the Afghan government and other stakeholders,” said Emily Horne, a spokeswoman for the National Security Council.

Under the peace agreement, all foreign forces were to leave Afghanistan by May 2021 in exchange for security guarantees from the Taliban, including their severing of ties with al-Qaeda and engaging in talks with the Afghan government. And while talks between the Taliban and the Afghan government have been ongoing for several months, little progress has been made amid the backdrop of increasing violence by the Taliban.
