SEOUL, Sept 14 (Reuters) - A top U.S. diplomat expressed

regret on Sunday over a U.S. immigration raid that detained more

than 300 South Korean workers, proposing making the event a

turning point to strengthen bilateral relations, South Korea

said.

Deputy Secretary of State Christopher Landau met First Vice

Foreign Minister Park Yoon-joo on Sunday, the foreign ministry

said in a statement.

Landau mentioned President Donald Trump's decision that the

Korean workers would not face any disadvantages when they

re-enter the U.S., the ministry said.

After about a week of detention at a U.S. immigration

detention facility, the Korean workers returned home on Friday.
