"Just been doing some quick checks on Statsguru and it looks like Pakistan have dominated India, Sri Lanka and Bangladesh throughout their history in all formats, with the exception of T20s against India, which there has only been 2, both in the 2007 T20 world cup. Pakistans TEST record vs other Asian teams (1952-2012: home, away and neutral) vs India: PD: 59, WON: 12, LOST: 9, DRAWN: 38 vs Sri Lanka: PD: 40, WON: 16, LOST: 9, DRAWN : 15 vs Bangladesh: PD: 8, WON: 8, LOST: 0 Pakistans ODI record vs other Asian teams (1972-2012: home, away and neutral) vs India: PD: 121, WON: 69, LOST: 48, NR: 4 vs Sri Lanka: PD: 128, WON: 77, LOST: 47, TIED: 1, NR:3 vs Bangladesh: PD: 31, WON: 30, LOST: 1 Pakistans T20 record vs other Asian teams (2006-2012: home, away and neutral) vs India: PD: 2, WON: 0, LOST: 1, TIED: 1 vs Sri Lanka: PD: 9, WON: 6, LOST: 3 vs Bangladesh: PD: 5, WON: 5, LOST: 0 Just shows that overall, Pakistan have been dominant against fellow Asian teams!"
