Partha has withdrawn its troops from Baltia after five years of occupation.Earlier this year the country of Cardena bagan shipping mules to Baltia's resistance fighters to facilitate transport of weapons across Baltia's mountains to the battle area. Carenda's diplomats now claim that without Carenda's aid to Baltia's resistance fighters, Partha would not have withdrawn.Which of the following, if true, cast most serious doubt on the accuracy of the assertion of Carenda's diplomat?
（A）No precise figures are available concerning the number of mules shipped to Baltia.
（B）During the past year, Carenda shipped weapons and food, as well as mules, to resistance fighters in Baltia.
（C）Last year a new government took power in Partha and decided that national interests were not served by the occupation of Baltia.
（D）Two years ago Partha had no plans to reduce its forces in Baltia.
（E）Resistance fighters in Baltia fought for five years against Partha's occupying troops.


正确答案是C， 但是不明白Carenda's diplomat 说的话到底什么意思？麻烦各位进来的同志们帮我写一下逻辑链，并给出准确分析，谢谢！！！

P 把在B的军队撤了回来。 在今年的早些时候C运输了一些骡子到B来支持B对P的抵抗势力。 C的外交部因此申明，如果没有C的支持，P就不会退兵。 问削弱

答案是：P今年新政府上台，新政府决定P对B的占领不能带给P任何国家利益上的好处
