Leaders of major Asian cities issued a declaration Thursday, outlining 15 joint projects that include the development of the region's air industry, online education and environmentally friendly vehicles.

The Tokyo Declaration came at the conclusion of the two-day inaugural meeting of the Asian Network of Major Cities 21, which brought together mayors and senior officials from 11 regional capitals in Tokyo.

The declaration -- signed by representatives from Beijing, Delhi, Hanoi, Jakarta, Kuala Lumpur, Tokyo, Manila, Seoul, Singapore, Taipei and Yangon -- affirms the importance of the Asian region within the global community and the need for a mechanism for cooperation among the cities.
