Our strategy is to build preferred Brands with scale positions in the most attractive markets globally. Concentrating growth in the largest markets means IHG and owners can operate more efficiently and benefit from enhanced revenues and reduced costs. Our key markets include large developed markets such as the US, UK and Germany, as well as emerging markets like China and India.
The US is the largest market for branded hotels, with 3.38 million rooms, accounting for 69 per cent of all US rooms available. The segment in the US with the greatest share is midscale, with 1.38 branded hotel rooms, and IHG's Holiday Inn brand family, comprising Holiday Inn, Holiday Inn Express, Holiday Inn Club Vacations and Holiday Inn Resort, is the largest branded in this segment.
In China, IHG sees the greatest opportunity for growth of any single country and our strategy has been to enter the market early, to develop our relationship with key local third party owners and grow our presence rapidly. In a country with 659,000 branded hotel rooms, IHG is the largest international hotel company with over 61,000 rooms across our brands and more than 50,000 in the planning phase or under construction. This rapid pace of openings for IHG has been in anticipation of increasing demand for hotels, driven by a large, emerging middle class and growing domestic and international travel.
IHG is also focussed on developing in other high priority markets. We seek to develop our portfolio of brands in those markets which will be sources of strong hotel demand in the future. We have continued to build our position in these markets in the last year. For example, we increased the distribution of our core brands in India, building upon the leadership position of Holiday Inn. In Russia and the Commonwealth of Independent States (CIS), there are opportunities for new construction and conversations as well as strong demand for branded hotels. IHG continues to adapt its business model by market, choosing partnerships and joint ventures where appropriate.
Outside the largest markets, we focus on building presence in key gateway cities where our brands can generate revenue premiums from high business and leisure demand.
During 2012, we opened 33,922 rooms in 26 countries and territories, and signed a further 53,812 rooms into our development pipeline (hotels in planning and under construction but not yet opened) across 33 countries and territories. As part of our ongoing commitment to maintaining the quality of our brands, we removed 16,288 rooms during the year. As at 31 December 2012, IHG had the second largest pipeline in the industry, with 169,030 rooms in 1,053 hotels across 60 countries and territories. This represents a market share of 12 per cent of all hotels under development, including those that are independent or unaffiliated with a brand.
