[1] Upon returning to China, Luo continued to work in the steel industry, first being sent to the First Ministry of Machine-Building, a state-run department in charge of machines, telecommunications, and shipbuilding.
As a technical specialist, Luo, like many others in his field, were displaced from their posts during much of the Cultural Revolution, and sent to perform manual labour at a May 7 Cadre School.
[1] In October 1978, as part of a nationwide reshuffle following the demise of the Gang of Four, former First Machine-Building minister Duan Junyi took on the post of party chief of central Henan Province.
[2] Luo oversaw a diverse portfolio with jurisdiction over law enforcement and internal security, as well as "comprehensive social management", a nebulous new phrase that essentially meant asserting control and preventing organized protests and social disturbances; as part of his responsibilities, he was tasked by Jiang Zemin to head the 610 Office, an extrajudicial organ established to suppress the spiritual group Falun Gong.
The Standing Committee was expanded from seven members to nine in 2002, some say as a result of then-Party General Secretary Jiang Zemin attempting to stack the body with his supporters.
Regarded as the "security chief" of the country, Luo implemented the "strike hard" campaign against extremism in Xinjiang and against organised crime, increasing the harshness of sentences; some suggest that this policy led to increased executions; it was said that Luo had personally directed the suppression of "illegal organisations" such as the Falun Gong movement and protests such as that at the Pubugou Dam protest in 2004.
During his tenure, Luo was seen to have warned party officials to rein in judicial independence and but also pay heed to the international implications of legal activities in China, while also expanding "rule by law".
On December 17, 2009, Argentinian Federal Judge Octavio Araoz de Lamadrid issued a national and international Interpol warrant for the detention of Luo Gan, along with Jiang Zemin.
The warrant was issued with basis on the investigation of 17 testimonies of Falun Gong practitioners victims of persecution, along with reports by Human Rights Watch, Amnesty International, and the UN detailed in case Nº 17885/2005.
