As Trump and Xi talk, China surges ahead with its AI ambitions

In the expansive grasslands of Inner Mongolia, farmers are picking plump potatoes alongside new neighbours: huge, rectangular blocks that will fuel China's AI platforms. Ulanqab, with its steppes and volcanoes, is an unlikely digital frontier. For years, it has been China's official potato capital. But now its fields have also become construction sites for a slew of data centres, as Donald Trump and his Chinese counterpart Xi Jinping meet to discuss AI safety among other things. Hundreds of workers in yellow helmets carry heavy equipment into the building site as welding sparks fly off metal scaffolding.
