VIENTIANE - Chinese Premier Li Keqiang's upcoming tour to Laos will significantly enhance relations between China and the Association of Southeast Asian Nations (ASEAN) and China-Laos comprehensive strategic cooperative partnership, Chinese ambassador to Laos said on Monday.

During his stay in Laos on Sept 6-9, Li will attend the 11th East Asia Summit in Vientiane and pay an official visit to Laos.

Guan Huabing, Chinese ambassador to Laos, told Xinhua in a recent interview that since this year marks the 55th anniversary of the establishment of China-Laos diplomatic ties and the 25th anniversary of the establishment of the China-ASEAN dialogue relationship, Li's visit is expected to push forward regional integration in East Asia.

Prior to his official visit to Laos, the Chinese premier will arrive at Vientiane on Tuesday to attend the 19th China-ASEAN Summit to commemorate the 25th anniversary of the China-ASEAN dialogue relationship, the 19th ASEAN Plus Three (China, South Korea and Japan) Summit and the 11th East Asia Summit.

Guan noted that the highly compatible strategies between China's initiative on the construction of the Silk Road Economic Belt and the 21st Century Maritime Silk Road (the Belt and Road initiative) and Laos' strategy of turning itself from a "landlocked" country into a "land-linked" country will expand the space for further deepening cooperation between the two sides.

The two countries have also enjoyed close cooperation on international and regional affairs and worked together to make positive contributions to maintaining peace, stability and development in the region.

Guan said China believes that Laos, which took over the rotating chair of ASEAN immediately after the establishment of the ASEAN Community on Dec. 31, 2015, will play an important role in boosting regional cooperation and maintaining regional peace and stability. China will continue to fully support Laos' role as ASEAN's chair for 2016, he added.

Lao President Bounnhang Vorachit visited China in May shortly after he was elected president of Laos in April and became general secretary of the Central Committee of the Lao People's Revolutionary Party in January.

During the visit, Chinese President Xi Jinping and Bounnhang stressed the importance of building an unshakable community of common destiny between the two sides, drawing a blueprint for the development of ties between the two countries and the Communist Party of China and the Lao People's Revolutionary Party.
