BEIJING – Noodles will be served by a robot — just one of the many ways that China is aiming to keep the Olympics free of COVID as an estimated 13,000 international athletes and journalists descend on Beijing, China’s capital, for the Winter Olympic Games that start on February 4.

Hosting the Olympics presents a massive challenge for China, where for the last two years, authorities have implemented some of the most rigorous prevention COVID policies in the world. The country has closed its borders to nearly all travelers and locked down cities over just a handful of infections.

The global surge in omicron cases has also put authorities on edge. In nearby Tianjin – a 20-minute high-speed train ride away from Beijing – authorities tested all 14 million residents after a few dozen omicron infections were discovered.
