Well, they look, smell and taste like burgers made from meat, but they're made from soya beans. Nut burgers also delicious...but made from nuts, of course.
In 2018 President Donald Trump imposed tariffs on Chinese exports worth $60bn a year, forcing China to retaliate by slapping duties on American soya beans.
Stocks of soya beans, China's biggest farming import, have doubled since 2018, to 39m tonnes, and are projected to hit 42m tonnes by the end of the season.
