U.S. Secretary of State Antony Blinken says Washington is reconsidering its North Korea policies, leaving the door open to every possible choice, including means to put pressure on communist state. 

He made his remarks in a press conference following the two plus two security talks involving U.S. Secretary of Defense Lloyd Austin and their Japanese counterparts in Tokyo on Tuesday. 

Blinken said the Joe Biden administration is currently reviewing U.S. strategies on North Korea, adding U.S. think tanks, outside experts and former government officials and others are discussing how to reduce risks related to North Korea. 

The U.S. secretary said various means of pressure, or obstinate means, against the North are all under reconsideration, adding the U.S. plans collaborate with allies and partners. He said the U.S. will particularly respond to the North’s nuclear missile program and human rights violations. 

Blinken also affirmed the U.S. has been attempting to contact the North through multiple channels since mid February, but has received no response yet. 

Regarding the warning from the powerful sister of North Korean leader Kim Jong Un against Seoul and Washington earlier in the day, Blinken said he is not familiar with such a rhetoric but described it as “interesting,” indicating the allies’ need to jointly respond over North Korean issues.
