WASHINGTON, 22 May, 2021, (TON): South Korean President Moon Jae-in said in a joint press conference with President Joe Biden that the United States agreed to end the flight range guidelines that limited South Korea's missiles to 800 kilometers (450 miles). 

"It is also with pleasure that I deliver the news on the termination of the revised missile guidelines," South Korean President said during press conference at the White House on Friday. 

The two sides also agreed to further reinforce their combined defense posture, Moon said. 

South Korea first agreed to the missile guidelines in 1979 in return for American technological aid in developing its first ballistic missiles. After the South’s repeated requests for a revision, American officials agreed to extend the range to 300 kilometers from 180 kilometers in 2001. Another revision in 2012 followed a 2001 extension of the original 180-kilometer range limit to 300 kilometers and then 800 kilometers. 

American restrictions on ballistic missiles do not apply to South Korean cruise missiles.
