The landscaping work on the Aspire Zone is being done by Nakheel Landscapes, a Qatari company.

Qatari companies pay among the highest dividends in the region; these are announced with the first quarter corporate results.

Meanwhile, a Qatari company has bought the bridge and is insisting that Pop uses a new kind of paint.

Also, some analysts say Qatari companies may see relatively little benefit from mega-projects if they are too small to handle the deals.

Shares in some other government-affiliated Qatari companies with 25 percent foreign ownership limits also surged on expectations they would take the same action.

Currently, listed Qatari companies impose ceilings on foreign ownership that are usually limited to 25 percent, though some have raised their ceilings above that level.

The Qatari company's 35.5 percent holding in Paiton could be valued at more than $1 billion, Bloomberg reported.

However, Britain's Financial Conduct Authority (FCA) said it failed to reveal another 322 million pounds in two "advisory services agreements" with the Qatari company.

A little under two-thirds of the 20 most valuable Qatari companies rose on Monday, including Qatar Islamic Bank, which added 2.6 percent.
