China has rolled over a $2 billion loan to neighboring Pakistan, the country's caretaker Finance Minister Shamshad Akhtar confirmed in a response to Reuters on Thursday.

The $2 billion loan was due in March and has been extended for one year, Geo News, which first reported the news, cited sources in the Pakistan Finance Ministry. Beijing had communicated the decision to Islamabad, it added.

Pakistan's cash-strapped economy is struggling to stabilize from a financial crisis and secured a $3 billion standby arrangement from the International Monetary Fund (IMF) last summer.

Pakistan's vulnerable external position means that securing financing from multilateral and bilateral partners will be one of the most urgent issues facing the next government, ratings agency Fitch said last week.
