As has been recently reported by the U.S. State Department:

• The Republic of Korea is one of only a handful of East Asian countries that has acceded to the Hague Abduction Convention.
• The Republic of Korea acceded to the Convention in December 2012, and the Convention went into force for the Republic of Korea on March 1, 2013.
• The Convention will not enter into force between the Republic of Korea and the United States, however, unless the United States decides to accept the Republic of Korea as a partner.
• The Department currently is conducting a review of the Republic of Korea’s implementation of the treaty, including its domestic legislation and institutions responsible for executing the country’s responsibilities under the Convention, in order to determine whether the United States should accept the Republic of Korea as a partner under the Convention.
