In 1999, after many years of negotiations, China and Vietnam signed a border pact. There was an adjustment of the land border, resulting in Vietnam giving China part of its land which was lost during the battle, including the Ai Nam Quan Gate which served as the traditional border marker and entry point between Vietnam and China, which caused widespread frustration within Vietnamese communities. Vietnam's official news service reported the implementation of the new border around August 2001. In January 2009 the border demarcation was officially completed, signed by Deputy Foreign Minister Vu Dung on the Vietnamese side and his Chinese counterpart, Wu Dawei, on the Chinese side. Both the Paracel (called Hoàng Sa in Vietnam, Xīshā in China) and Spratly (Trường Sa in Vietnam, Nansha in China) islands remain a point of contention.
