Two fugitive officials were brought back to China as the first battle of a new anti-graft campaign code named "Sky Net" to hunt down officials who have fled the country rolls on, China's top disciplinary watchdog announced Saturday.

Pang Shunxi, the former director of Tianjin branch of the State Administration of Taxation and An Huimin, the former manager of the Tianjin-based Han International Trade Co Ltd, were escorted back on Saturday afternoon after they gave themselves up to the Chinese Embassy in Laos, according to the Central Commission for Disciplinary Inspection (CCDI) of the Communist Party of China.

The two fled to the Southeast Asian country after they were investigated for corruption and bribery in December 2014.

The arrests are believed to be the first under "Sky Net," which is a new anti-graft campaign following the previous operation "Fox Hunt 2014," in which 680 officials who fled overseas were arrested.

Jointly undertaken by the Organizational Department of the CPC Central Committee, the Supreme People's Procuratorate, the Ministry of Public Security (MPS) and the People's Bank of China, the new campaign will focus on arresting officials suspected of corruption and cracking down on fake passports and underground banks, in addition to recovering assets involved in criminal cases, according to media reports.

The MPS will continue to head the "Fox Hunt" campaign in 2015 as part of the "Sky Net" operation.

It also calls for suspects at-large to give themselves up as soon as possible for a more lenient punishment.
