OSLO, July 6 (Reuters) - Norway's $1.4 trillion sovereign wealth fund said on Thursday it has excluded Power Construction Corp of China Ltd from its portfolio.
The Chinese company was excluded due to "unacceptable risk of the company contributing to or being responsible for serious environmental damage."
The fund, one of the world's largest, also said it had placed Petrofac Ltd under observation for a period of three years. (Reporting by Victoria Klesty)
