North korea agrees to shut missile site says moon

I think there may be some confusion here. As of my knowledge cutoff, there has been no official announcement from North Korea or the Moon administration (referring to the government of South Korea led by President Moon Jae-in) about North Korea agreeing to shut down a missile site.

However, there have been some reports of diplomatic efforts and negotiations between North Korea and the United States, as well as between North Korea and South Korea, aimed at reducing tensions and addressing concerns over North Korea's nuclear and missile programs.

In June 2018, North Korea and the United States agreed to work towards the "denuclearization of the Korean Peninsula" in a joint statement following a summit between North Korean leader Kim Jong-un and US President Donald Trump. Since then, there have been several rounds of talks and negotiations between the two countries, but no concrete agreements have been reached on specific issues such as the shutdown of missile sites.

It's possible that you may be referring to a specific report or article that I'm not aware of. If you could provide more context or clarify what you're referring to, I'd be happy to try and help you further.
