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.
In the tests conducted at least a dozen times between 1961 and 1962, rice blast fungus was released over rice fields and data was collected on how it affected rice production, Kyodo said, citing the documents.
