Top 2 Largest Chinese Embassies, Including One in Seoul

Embassy of the People's Republic of China in the USA

Embassy of the People's Republic of China in South Korea
The Embassy in South Korea is located on a site in Myeong-dong with a very long history, starting from the Chinese Legation in 1890s,
followed by the Japanese Legation in Seoul - Embassy of the Republic of China in Korea - Embassy of the People's Republic of China in Korea.
That is the reason why there are so many overseas Chinese living in that area...
That building is the second largest among Chinese diplomatic missions, after the
Embassy of the People's Republic of China in Washington D.C.

Bird's-eye view of the Chinese Embassy in London currently under construction
I heard that this one will be even larger.
By the way, while the Chinese build beautiful embassies in the US and UK,
why did they build the embassy in Korea so uglily? ㅡㅡ
