Abu Dhabi Commercial Bank may be owed $1.9bn by Dubai World, making it the largest creditor outside the emirate to the state company seeking to reschedule debt, said two people familiar with the companies.

'We are in touch with Dubai World, and we have been in discussions more than once today and yesterday,' Ala’a Eraiqat, the chief executive officer of the third-largest lender in the United Arab Emirates, said in a telephone interview yesterday. He declined to comment on specifics. 'We have a lot of assurances which is a good thing.'
