Convening nearly 40 foreign leaders and representatives from more than 150 countries, the Second Belt and Road Forum for International Cooperation, which opens in Beijing on April 25, testifies to a growing aspiration for collaboration amid rising unilateralism and protectionism. The conspicuous increase in the size of foreign participation compared with the inaugural forum two years ago corroborates United Nations Secretary-General Antonio Guterres' earlier comment that the Belt and Road Initiative, like the UN Millcnnium Development Goals, is a public good for the entire world.
