As from Jan. 1, 2010, Vietnamese and Cambodian citizens holding ordinary passports valid for at least six months will enjoy visa exemption if they enter or transit the other country, according to the Foreign Ministry’s Consular Department.
Those citizens of one country may stay in the other country for up to 30 days instead of 14 days as before, says the department.
Vietnam and Cambodia signed an agreement on visa exemption for ordinary passport holders on November 4, 2008. The agreement, which took effect on December 5, 2008, stipulated that these holders are exempted from visas if they stay in the other country for not more than 14 days.
