China has witnessed significant improvement in its economic development, overall national strength and the people's living standards over the recent 30 years, he said.
He said the destinies of China and the world are closely correlated with each other as China's development is indispensable to the world and the world's stability and prosperity is indispensable to China.
He added that China will continue its efforts in promoting enduring peace and common prosperity so as to build a harmonious world.
China, which has scored remarkable achievements in its social-economic development over the three decades, has already become an important factor in world's economic growth, said the leaders of the four European countries.
They said they appreciated China's positive role in international and regional affairs, saying China is a steadfast force in maintaining world peace and stability.
They also expressed willingness to strengthen communication and cooperation between China and Europe so as to make joint efforts with the country in promoting the world's peace and prosperity.
Finally, while introducing the top political advisory body in China and the country's system of multi-party cooperation and political consultation, Jia said the CPPCC has played a vital role in China's political life and its contacts with other countries.
An important task of the CPPCC is to promote mutual understanding and friendship between the Chinese people and the people around the world, he said.
The CPPCC, which has forged friendly association with 211 institutions in 121 countries around the world and 12 international or regional organizations, highly values its communication and cooperation with the parliaments of the four European countries, Jia said, adding it is ready to devote more efforts to improving bilateral ties between China and European nations.
