In 2009, the government diversified its economic plans. Served by high oil prices, the country's non-oil and gas GDP outstripped that attributable to the energy sector. Non-oil and gas GDP now constitutes 64% of the UAE's total GDP. This trend is reflected in Abu Dhabi with substantial new investment in industry, real estate, tourism and retail. As Abu Dhabi is the largest oil producer of the UAE, it has reaped the most benefits from this trend. It has taken on an active diversification and liberalization program to reduce the UAE's reliance on the hydrocarbon sector. This is evident in the emphasis on industrial diversification with the completion of free zones, Industrial City of Abu Dhabi, twofour54 Abu Dhabi media free zone and the construction of another, ICAD II, in the pipeline. There has also been a drive to promote tourism and real estate with the Abu Dhabi Tourism Authority and the Tourism and Development Investment Company undertaking several large-scale development projects. These will be served by improved transport infrastructure, with a new port, an expanded airport and a proposed rail link between Abu Dhabi and Dubai all in the development stages.
