Qatar, the world’s largest exporter of liquefied natural gas, is ensuring its key property firms weather the global crisis, which has hit nearby Dubai hard, by pushing through defensive mergers and using Diar to invest in them.
Diar holds a 45% stake in Barwa Real Estate company, the sixth-largest developer in the Gulf Arab region by market value, which is taking over rival Alaqaria in a government-ordered deal.
Barwa also plans to sell assets through 2010 and 2011 to meet its obligations.
Qatar has said it will keep spending to maintain domestic growth momentum as well as acquiring overseas assets, Reuters said.
Qatar, which is eyeing a $ 100bn budget for new projects over the next four years, issued QR10bn ($ 2.75bn) worth of eight-year conventional and Islamic bonds to local banks earlier in June.
Recently, HE the Minister of Finance Yousef Hussein Kamal said Qatar may spend around $ 100bn within the next four years on different projects.

“The main projects are roads, sewage treatment, water treatment and infrastructure like ports and airports,” he told reporters on the sidelines of a Turkish-Arab economic forum in Istanbul.
