As　a　unique　continental　archive,　speleothem　has　been　widely　used　in　reconstructing　paleoclimate　change.　However,　the　interpretation　of　Chinese　speleothems　delta　O-18　has　remained　a　subject　of　debate.　Recently,　a　Community　Atmosphere　Model　version　3　(CAM3)　study　indicated　that　the　stalagmite　delta　O-18　from　eastern　China　reflected　the　Indian　summer　monsoon　(ISM)　intensity　rather　than　the　East　Asian　summer　monsoon　(EASM)　intensity　during　Heinrich　events.　Here,　we　present　a　high-resolution　speleothem　delta　O-18　record　from　Xianglong　Cave　in　Shaanxi　province,　China,　covering　the　period　of　25.5-10.9　ka　BP.　The　XL15　record　shows　similar　variations　with　ice　core　record　from　Greenland　and　other　climate　records　from　China　and　India　on　millennial　scale,　including　Heinrich　2　(H2),　Heinrich　1　(H1),　Bolling-Allerod　(BA)　and　Younger　Dryas　(YD)　events,　supporting　the　connection　between　the　Asian　monsoon　and　northern　high　latitude　climate.　The　delta　O-18　amplitude　of　our　record　is　larger　than　or　similar　to　the　stalagmite　delta　O-18　records　from　India　during　these　events.　In　addition,　differences　of　stalagmite　delta　O-18　in　eastern　China　and　the　ISM　region　were　observed　on　glacial-interglacial　as　well　as　decadal　timescales.　That　means　the　ISM　is　not　the　sole　controlling　factor　of　Chinese　stalagmite　delta　O-18　during　Heinrich　events.　When　subtracting　the　Indian　stalagmite　delta　O-18　series　from　our　XL15　record　during　H1　period,　we　found　a　significant　negative　correlation　with　sea　surface　temperature　(SST)　record　of　Western　Pacific　Warm　Pool　(WPWP).　Consequently,　our　study　suggests　that　the　Chinese　stalagmite　delta　O-18　is　controlled　by　both　the　ISM　and　EASM　on　orbital-,　millennial-,　and　decadal　timescales.
