 Karzai's relations with neighboring Pakistan were good, especially with the Awami National Party (ANP) and Pakistan Peoples Party (PPP).He often describes his nation and Pakistan as "inseparable twin brothers", a reference to the disputed Durand Line border between the two states, despite the many border skirmishes that occurred during his presidency.In December 2007, Karzai and his delegates traveled to Islamabad, Pakistan, for a usual meeting with Pervez Musharraf on trade ties and intelligence sharing between the two Islamic states.
