"If you look globally, the upside is in emerging markets and the Middle East is a key component of that," Makram Azar, global vice-chairman for investment banking at Barclays, told Reuters.

"We are committed to the Middle East. I do not see why our strategy would change," Azar said in an interview.

Last week's appointment of retail banker Antony Jenkins as Barclays group chief executive could see a shift from riskier investment banking, analysts said, as the lender tries to recover from an interest rate-rigging scandal that brought down former CEO Bob Diamond.

Barclays is also the subject of a British regulatory inquiry into payments to Qatar's sovereign wealth fund linked to its participation in an 11 billion pound ($17 billion) refinancing of the bank at the height of the financial crisis in 2008.

Azar would not comment on whether that inquiry might affect its business in the region.

While investment banking has been at the heart of recent troubles at Barclays, the unit delivered 54 percent of underlying first-half group profit.

BUSY ADVISING

Middle Eastern deal activity has been picking up after a subdued period. Cash-rich Gulf Arab sheikhs and governments are buying European assets, lured in part by attractive valuations due to weak markets.

"There is a pick-up in M&A activity in the MENA (Middle East and north Africa) region, led to a large extent by Qatar and Abu Dhabi, pouring billions of dollars into Western companies which have been hard hit by massive writedowns," Azar said.

"The environment in Europe is still challenging but there are names that were beaten up and are now trading at attractive levels. This presents an opportunity for Gulf investors."

Barclays leads M&A advisory rankings in MENA, according to Dealogic, with $4.7 billion of deals this year, followed by Goldman Sachs (GS.N) at $3.7 billion and Credit Suisse (CSGN.VX) on $3.5 billion.

Gulf investment into Europe almost froze in 2010 and 2011 because of confusion over the euro zone debt crisis and losses suffered on previous overseas deals completed at the height of the 2008 crisis - most notably sovereign funds from Abu Dhabi and Kuwait investing in U.S. banks.

Also, Qatar's sovereign wealth fund became an unexpected kingmaker in the Glencore-Xstrata (GLEN.L) (XTA.L) deal after spending more than 3 billion pounds raising its stake to 12.3 percent.

Other regional players are also involved, with Abu Dhabi fund Mubadala MUDEV.UL acquiring a 5.6 percent stake in Brazilian conglomerate EBX for $2 billion and Almarai 2280.SE, Saudi Arabia's largest dairy company, buying Argentine farm operator Fondomonte S.A. for $83 million.

Gulf Arab investors are also targeting options closer to home as they look for places to park their cash.

"The oil price is at a high level, higher than the levels at which Gulf government budgets are based on, and this excess revenue needs to be invested," Azar said.

"Some of it is being channeled indirectly into the region in the form of investments such as Qatar Telecom's bid for Wataniya and the rest is invested outside the region."

Barclays has been advising Qtel's QTEL.QA $2.2 billion bid for the 47.5 percent of Kuwaiti telco Wataniya (NMTC.KW) it does not own. The Qatari group has also increased its stake in Iraqi firm Asiacell to 60 percent in a $1.47 billion deal in June.

Gulf-based banks are also said to be keen to acquire stakes in Egyptian lenders being offloaded by French owners who want to divest assets to shore up capital positions at home.

Azar said further opportunities would emerge this year.

"The bank worked on several deals in the region worth around $4.7 billion and the year is not over yet. We are now looking at a number of additional deals in the pipeline."
