"The main goal of these efforts is to make the transit of goods along the Asia-Europe route as fast as possible, economically viable and to form a powerful transport hub in the Russian Far East, which will help meet the needs of the entire Asia-Pacific region", he said.

The 31st ASEAN Summit is the most important event of the Association of Southeast Asian Nations that groups Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, Thailand, and Việt Nam.
More such meetings with visiting leaders are being arranged on the sidelines of the summits.
Modi is also likely to participate in special celebrations of the 50th anniversary of ASEAN, Regional Comprehensive Economic Partnership (RCEP) Leaders' Meeting and ASEAN Business and Investment Summit.
