SCMP Weekend Reads Roundup Covers China's 3-nm Chip Path and Trump-Xi Meeting Plans

A South China Morning Post weekend roundup compiled five stories readers may have missed, among them an account of Chinese researchers pursuing an alternative route to 3-nanometer chips that relies on older lithography equipment. The chip item was illustrated with a photograph of an assembly engineer working on a TWINSCAN deep ultraviolet (DUV) lithography system at ASML in Veldhoven, the Netherlands, credited to Reuters. The same collection of weekend reads also addressed US President Donald Trump's hosting plans for a visit by Chinese leader Xi Jinping, and included a piece on how much sex couples should have. The roundup was published by the South China Morning Post under its world news section. No further specifics from the individual stories — such as the researchers' institutional affiliations, the technical details of the proposed lithography approach, the timing of the planned Xi visit, or the findings of the relationships article — were provided in the available material. The aggregation format presents the chip research and the diplomatic hosting arrangements as the most prominent of the five items, with the DUV lithography image serving as the lead visual for the chip story.
