Pham made the call while delivering his remarks at the inaugural session of the third Voice of Global South Summit in virtual format on August 17.
The event, hosted by Prime Minister Narendra Modi, is themed "An Empowered Global South for a Sustainable Future".
Pham suggested Global South countries should have a common vision and thinking, action, and approach that are global, comprehensive, and inclusive.
They should push for stronger ties in the spirit of solidarity and unity to seize opportunities, overcome challenges, resolve difficulties and move towards a sustainable and prosperous future for all, he emphasized.
Pham underlined the need to effectively and substantially promote the reform process of regional and global governance institutions, with a focus on reforming the United Nations towards a more democratic and effective manner, enhancing the multilateral trading system with the World Trade Organization (WTO), and minimizing trade barriers and unfair competition.
It is necessary to effectively mobilize and use all social resources to successfully implement the United Nations Sustainable Development Goals (SDGs), he asserted.
The PM called on countries to promote their pioneering role in ensuring food security, environmental protection, natural disaster prevention, climate change adaptation, and fostering the development of green economy, digital economy, and circular economy on the principles of equal access, fairness, autonomy and self-reliance.
He stressed the importance of creating new driving forces for growth, especially in science and technology, innovation and entrepreneurship, considering it as the focus of all cooperation mechanisms and initiatives.
Besides, Pham urged countries to step up South-South trade and investment, and develop South-South science and technology markets and an innovation ecosystem connecting the state, schools, and businesses and enhancing regional linkages.
Leaders from Global South countries affirmed their commitment to global multilateral system and international law, asserting the necessity to promote international solidarity and cooperation, and reform of multilateral mechanisms.
They vowed to accelerate the implementation of SDGs through strengthening financial resources, sharing development experiences, enhancing digital transformation, developing private economy and boosting technology cooperation.
This year's summit brought together leaders of more than 100 countries in the Global South to discuss a range of complex challenges that continue to affect the world, such as conflicts, food and energy security crises, climate change-all of which disproportionately affect developing countries in a severe manner./.
