Japanese partners and allies have taken substantial steps on information security and procedures to protect sensitive information that could potentially be shared between the US and Japan, the senior administration official said.
"You will see over the course of the next few days that we are stepping up our intelligence cooperation," the senior administration official said, amid a state visit to the US by Japanese Prime Minister Fumio Kishida.
The US maintains a "fundamental goal" of being able to share the most important information with Japan as a close ally, the senior administration official said.
