Punjab National Bank on Tuesday obtained permission to start its operations in Afghanistan and plans to open offices in Dubai and Shanghai as well.

The Afghanistan government has authorised PNB to start banking operations through a representative office in Kabul.

"It is expected that PNB would start its work in a month or so," Ministry of External Affairs said in a release in New Delhi.

When contacted, a PNB spokesman told PTI that the bank's chief manager S K Mohanty will head the Kabul operations.

Mohanty along with other officials was in Kabul to complete the formalities, he said, adding the bank's operations would start in June.

PNB recently opened a representative office in London, he said.
