Nominally, it is China's, and its assets are American, but it enjoys preferential treatment from the China government. Its slogan looks like China's, its headquarters is also in China, and its founder is also from China (only from China, after all, people have a green card). So most people think it's from China, but from an economic point of view, it's still from the United States. Look at Baidu Encyclopedia's introduction to Baidu. Although its foreign color is extremely diluted there, its economic base is basically the same as Baidu.
