Vietnam on Wednesday asked South Korean authorities to strictly punish a Korean man who allegedly killed his Vietnamese wife on Tuesday.
The Vietnamese embassy in Seoul also asked South Korea to take measures to ensure safety of Vietnamese immigrants in the country.
The embassy conveyed condolences to the family of the murdered wife, Hoang Thi Nam, and raised a fund to support them.
Nam, 23, was stabbed to death by her 37-year-old husband Lim Chae Won with a knife at about 1 a.m. on Tuesday.
The brutal murder occurred at their house in Cheongdo County of North Gyeongsang, a province in eastern South Korea.
Nam gave birth to a baby boy 19 days prior to her death.
Nam's mother and aunt from Binh Thuan Province have left for South Korea to receive the body of the deceased.
The association of South Korean people in Ho Chi Minh City on Wednesday granted US$3,000 and two air tickets to fund their trip.
According to Nam's family, she was introduced to Lim by a Vietnamese friend in Ho Chi Minh City last year. After they got married, she arrived in South Korea in August 2010.
One day before the murder, "Nam called home saying she and her husband will take pictures of their son and send to the family to mark the boy's one-month birth anniversary," Tran Van Tri, Nam's brother-in-law, told Thanh Nien Wednesday.
Nam had told her mother several times that she did not get along with her mother-in-law and the couple decided to move out to live in an apartment near her husband's family.
"Nam and her husband had quarreled several times because Nam did not get along with her mother-in-law, but the couple reconciled soon," said Tri.
Byun Chang-bum, South Korean General Consul in HCMC, told Thanh Nien that the South Korean government has recently developed more policies to better serve international marriages, but this regretful incident happened beyond their expectation.
