CNOOC (China National Offshore Oil Company) has their headquarters in Beijing, just inside the Second Ring Road at Chaoyangmen.
The building was designed by American architectural firm KPF (Kohn Pederson Fox Architects), the firm behind the design of the Shanghai World Financial Center in Shanghai, the Rodin Museum in Seoul, and also the Architect-of-Record for the latest expansion of the Museum of Modern Art (MoMA) in New York City.
