China's top disciplinary watchdog said Friday that one-third of 100 people on its list of most-wanted fugitives who fled overseas were netted amid China's intense anti-graft drive.

China released a list of 100 wanted fugitives in April 2015 as it stepped up its worldwide fugitive hunt. Some 60 percent of the fugitives are wanted for corruption and bribery, China News Service reported in March.

Zhu Haiping, former official of Civil Aviation Administration of China's Hubei branch, turned himself in on Wednesday after he fled to the US in June 1998 to avoid being investigated for fraud, the Communist Party of China Central Commission for Discipline Inspection (CCDI) announced on Friday.

Separately, Guo Liaowu, a former official with Wuhan Iron and Steel Co who fled to Australia in August 2010, also delivered himself to police on Friday.

Together with Zhu and Guo, one-third of the 100 people on the list have been netted, and half of them were persuaded to come back to their home county, said the CCDI.

Persuasion is the most effective method to get the fugitives back at the least cost, compared with other measures such as suing in a foreign jurisdiction, Zhuang Deshui, a professor with Peking University, told the Global Times.

He added that the progress shows that China is determined to bust corruption officials through various methods and the country expects to see more fugitives busted amid the enhancing anti-graft effort.

In addition to further promoting the operations of "Fox Hunt" and "Sky Net" in 2016, the CCDI is currently conducting a new operation to regulate wrongful passport applications and is holding training classes on overseas fugitive hunting, the Xinhua News Agency reported in March.

China apprehended 857 fugitives hiding overseas in the "Fox Hunt 2015" campaign against suspected economic criminals, according to the Ministry of Public Security.
