Agence France Presse reports that “the US army conducted field experiments of biological weapons, which could harm rice cropping, in the Japanese island of Okinawa in the early 1960s, a press report said Sunday.”

“The same experiments were also conducted on the US mainland and in Taiwan, Kyodo news agency reported, citing US military documents it said it had obtained.”

“The US is ‘believed to have had China and Southeast Asia in mind in developing such crop-harming agents,’ the report stated.”
