The PRC asserts that lack of consensus over the 'one China' issue is preventing the reopening of official dialogue, but I believe the biggest problem is that the governments on both sides want to emerge as the winner, and this affects their willingness to negotiate, and the possible outcomes.
『一個中國』議題沒有共識影響官方管道的開啟，只不過是中共的說法，我認為最大的問題應該是在於兩岸政府都想贏，這影響了談判的意願與可能的結果。
