ISLAMABAD (AP) — Pakistan's finance minister says he will step down amid a wave of criticism over the government's handling of a financial crisis that has sent prices soaring.

Asad Umar tweeted Thursday that Prime Minister Imran Khan offered him the energy portfolio in the Cabinet but he refused. He defended Khan's leadership, calling him the "best hope" for Pakistan.

Umar's resignation came days after he returned from talks in Washington with the International Monetary Fund. Pakistan is seeking an $8 billion bailout package, but the United States, which exerts major influence over the fund, has said it should not finance the billions of dollars in loans Pakistan has taken from China as part of Beijing's "Belt and Road" infrastructure initiative.
