Law enforcement officials must be prepared for a long struggle in the campaign to get corrupt officials who have fled abroad back to China, with 214 suspects being returned to the country as of the end of May, the Ministry of Public Security said.

The government launched operation "Fox Hunt" to go after suspects who left China seeking refuge abroad, often taking large sums of money with them, as part of a campaign led by President Xi Jinping to stamp out pervasive corruption.

Speaking at a meeting in the southern province of Guangdong, Meng Qingfeng, who is running the "Fox Hunt" campaign, urged his team to improve their investigating skills and employ a wide range of tactics to get suspects back to China.
