A Tibetan delegation of the National People's Congress of China has visited Boulder and Denver in Colorado State to enhance friendship and communication.

Heading the delegation, Qizhala, secretary of the Lhasa Municipal Committee of the Communist Party of China (CPC), said that the friendship between Lhasa and Boulder has been consolidated since the two cities became sister cities in April 1987.

The Boulder mayor, Suzanne Jones, welcomed the delegation. She said: "We have seven sister cities, Lhasa is one of our strongest and most treasured sister city relationships."

The two sides exchanged experience in integrating traditional industries like animal husbandry into modern ones, and developing environment-friendly industries and clear energy projects.

The delegation also met with Bill Cadman, president of Colorado Senate.
