This is exactly the logic of the one who back stabbed his comrade. Remember that before 1979, Vietnam and China were still allies. You said like Vietnam and China were enemy before. All the Vietnamese feel very disgusting about China until today , a traitor who sold his brother for money. China won't never be Vietnamese allies anymore.
@@binhu4083 Vietnam did not intent to attack China , so your purpose of dragged down Vietnam economy and prevent southern threat have no meaning. This war only caused hundred thousands of death and economic loss for both side. And it was all Chinese fault.
