With a goal for zero accidents zero pollution and zero casualties, the Chinese oil company always puts an emphasis on safety, environment and health and tries its best helping the local communities where it is present, Sun said.

Apart from being a job creator for the local people, PetroChina also builds road, hospitals and schools in the countries where it operates.

China, over the years, has strengthened cooperation with Arctic countries in various fields.

On April 20, 2012, China and Iceland signed a framework agreement on Arctic cooperation.

During the APEC meeting in Beijing last year, China and Russia signed a number of cooperation agreements.

All these provide PetroChina with a good foundation for forging cooperation ties with partners from other countries, Sun said.
