Beijing demanded on Wednesday that Seoul reverse course on the planned deployment of an advanced US anti-missile system to "avoid more serious negative impacts".

The remark came after reports of access restrictions in China to television series from the Republic of Korea and amid simmering anger among Chinese citizens.

On Tuesday, the ROK Defense Ministry signed a land swap deal with Lotte Group for the Terminal High Altitude Area Defense system in the name of handling "threats" from Pyongyang. However, experts said that while the system is of no use in that sense, its radar can cover parts of China and Russia.
