China and Sri Lanka established diplomatic relations in 1957.
The two sides had exchanged high-level visits, strengthened political mutual-trust, expanded trade and economic cooperation and coordinated on international and regional issues, Wu noted.
China and Sri Lanka announced the development of an all-round cooperative partnership last year.
The National People's Congress will constantly play a positive role in promoting Sino-Sri Lankan ties, enhance exchanges and cooperation on legislation and supervision, deepen understanding and friendship between the two peoples, he acknowledged.
Lokubandara said China is "always a real friend" of Sri Lanka. He appreciated the support from the Chinese government and people, noting Sri Lanka will consolidate and further the existing friendly cooperation with China, including cooperation between the two parliaments.
He said that Sri Lanka will constantly pursue the one-China policy.
