BEIJING, March 12 (Xinhua) -- China aims to finish building a nationwide network to monitor air quality in its vast rural areas by the end of the year, an environmental researcher said.

"China attaches importance to its ties with Austria and is willing to make joint efforts with the Austrian side to continuously advance cooperation in various areas," he added.?

Medvedev said frequent high-level contacts and prompt exchange of views on bilateral ties and other major issues were of high importance in ensuring bilateral relations stayed on the right track.

Jiang said she believes there is little possibility that the visa waiver would result in an increase of illegal residents among foreign tourists.

Hua said the bilateral relation grew rapidly in recent years, while the friendly cooperation continued to expand and deepen in diverse fields.
