Unfortunately, it seems that the harder approach works better:
Taipei, March 9 (CNA) The number of Taiwanese involved in telecom fraud in South Korea has fallen sharply after reaching a peak of more than 400 in December 2009, the Ministry of Foreign Affairs said.
According to the ministry's statistics, the number of Taiwanese nationals arrested and imprisoned for telecom fraud in South Korea began to spike in September 2006.
The ministry's statistics from December 2009 show that the total number of Taiwanese detained in South Korea for fraud at that time exceeded 400, most of them young people who allegedly went to South Korea for tourism or to attend short-term study programs.
The number of arrests only fell after Seoul introduced more punitive measures for fraud. Currently, the number of Taiwanese under arrest or serving time for fraud in South Korean is fewer than 10.
Oh, this is related to two girls who went missing... and were found in a Korean jail for their participation in fraud rings. Would have been found earlier but the pintin -or English aliteration, as the press called it- of their names was not the same given by MOFA and what the Korean authorities had. See the importance of using recognizable pinyin? And for the eleventh time, IT IS NOT ENGLISH!
