An agreement to boost cooperation on nuclear fusion signed during Russian President Vladimir Putin’s visit to Beijing last week could see China and Russia join forces in the development of the nascent energy source, which is emerging as a key area of geostrategic competition across the globe. Experts say the significance of the agreement lies less in any immediate technological breakthrough and more in what it signals about the future direction of Sino-Russian cooperation in strategic energy technologies. It's not immediately clear what this cooperation in fusion will look like on the ground, but if it's anything comparable to Beijing-Moscow cooperation in the nuclear fission sphere, concrete projects are likely to come.
