ABU DHABI, Jan 12 (Reuters) - More mergers are likely in Abu Dhabi as institutions there tie up in ways that are positive for their business, Khaldoon Khalifa al-Mubarak, group chief executive of Abu Dhabi state fund Mubadala, said on Thursday.

"There's an appetite for more mergers. I expect to see mergers continue in a positive way in Abu Dhabi," Mubarak told reporters. He did not elaborate on which firms might merge.

Last June, the Abu Dhabi government said it would merge Mubadala and another state fund, International Petroleum Investment Co, responding to the impact of low oil prices by pooling their investment power and consolidating operations. Mubarak said on Thursday that the merger was in its final stages and would be completed within weeks.

Abu Dhabi's First Gulf Bank FGB.AD and National Bank of Abu Dhabi NBAD.AD are also completing a merger.

Mubadala may open offices in China and Asia if the need arises, Mubarak said. India has huge growth potential and Mubadala is looking at it seriously, he added.

He confirmed that Mubadala was in talks with Japan's SoftBank 9984.T to invest in a technology fund of up to $100 billion that the Japanese firm is putting together with Saudi Arabia and other interests.

He did not give details. A source familiar with the talks earlier told Reuters that Mubadala might invest between $10 billion and $15 billion, and that an agreement could be signed in the next few weeks.
