South Korea's Yonhap news agency, quoting a military official, said the system could be operational "as early as April".

China is also strongly opposed to the deployment of the system. The BBC's Stephen Evans in Seoul points to Chinese fears that it might be able to see deep into Chinese territory, which could shift the balance of power in the region. China and Russia have both raised concerns over the deployment of the system, saying its radar could penetrate deep into their countries. Last year, China's foreign minister said the system went "far beyond" the defence needs of the Korean peninsula and directly affected China's "strategic security interests".
There has also been an outpouring of anger by Chinese consumers against the South Korean retailer Lotte, which allowed Thaad to be installed on one of its sites.There has also been an outpouring of anger by Chinese consumers against the South Korean retailer Lotte, which allowed Thaad to be installed on one of its sites.
