Beijing is home to a great number of colleges and universities, including several well-regarded universities of international stature, such as Peking University and Tsinghua University (two of the National Key Universities). Owing to Beijing's status as the political and cultural capital of China, a larger proportion of tertiary-level institutions are concentrated here than in any other city in China, reaching at least 70 in number. Many international students from Japan, Korea, North America, Europe, Southeast Asia, and elsewhere come to Beijing to study every year.
