Cash-strapped Pakistan has received a rollover loan of $2 billion that matured last week from its "all-weather ally" China, finance minister Ishaq Dar said on Friday, a move that will help Islamabad secure the much-required bailout from the IMF. The rollover is one of the key requirements for Pakistan meeting its external financing needed for it to ink the staff-level agreement with the International Monetary Fund (IMF). "I am happy to confirm that this has been rolled over on March 23," Dar told parliament, adding that all formalities were completed. Pakistan, currently in the throes of a major economic crisis, is grappling with high external debt and dwindling foreign exchange reserves.
