China firmly opposes attempts by external forces to foment "color revolutions" in Central Asia, firmly opposes interference in other countries' internal affairs under the pretext of human rights, and firmly opposes any force that tries to disrupt the tranquil life of the people of the six countries, Xi said.

He pledged to increase trade between China and the Central Asian countries to $70 billion by 2030.

As the COVID-19 pandemic is still raging globally, Xi said, China will continue to provide vaccines and anti-epidemic supplies to Central Asian countries, and step up joint production and technology transfer with respect to COVID-19 vaccines and medicines.

He announced that in 2022, China will provide an additional 50 million doses of vaccines to Central Asian countries and set up traditional medicine centers in countries with such a need. China is also calling for the establishment of a China-Central Asia health industry alliance, he added.

Xi also announced China will provide grant assistance of $500 million to Central Asian countries in support of livelihood programs, and offer 5,000 places at seminars and workshops to help Central Asian countries train professionals in fields including health, poverty reduction for agricultural development and information technology.

The leaders of the five Central Asian countries spoke highly of the achievements from the development of ties with China over the past 30 years, and said their countries are ready to take the anniversary as a new starting point to build strategic partnership with China that features more profound meaning, fruitful results and long-lasting friendship.

They vowed to jointly safeguard the countries' core security interests and strategic interests, comprehensively advance Belt and Road cooperation, intensify pragmatic cooperation in the fields of trade, energy, high-tech and security, actively participate in the China-proposed Global Development Initiative and develop close communication and coordination in regional and international affairs.

The summit adopted a joint statement of the leaders of China and the Central Asian countries on the 30th anniversary of the establishment of diplomatic ties.
