Reuters has a story up, based on anonymous sources, that China has just approved a government developed strain of bt rice*. Bt crops express a protein isolated from Bacillus thuringiensis a bacteria used by organic farmers to control insects. The introduction of bt crops (primarily corn and cotton) has lead to substantial reductions in the use of insecticides. China plants more than 100,000 square miles of land with rice each year, so the environmental and economic** impact of being able to reduce insecticide applications would be substantial.
China is also in a unique position when it comes to commercializing any form of genetically engineered rice, as the world’s largest producer of rice, but only a small next exporter*** China stands to benefit from any improvements to rice, and is largely immune to pressure from food importing countries such as the members of the European Union. China has also invested (and continues to invest) billions of dollars in developing their own, publicly-funded, domestic crop research and breeding which has kept their per acre crop yields trending upwards, and now means they’re prepared to make the leap to genetically engineered food crops (they’ve had bt cotton for some time) with home-grown technology, killing any narrative about this being western tech foisted off on the developing world.
