加入条约 meaning in Chinese

accession to a treaty
adhere to the treaty

The conclusion is that cfc legislation in those countries , which do not specifically incorporate a treaty - overriding provision in their domestic legislations or do not include in their tax treaties a provision specifically allowing the application of their cfc rules , will inevitably contradict with their tax treaties
最后笔者得出的结论是：凡在国内法( cfc立法)中没有加入条约超越条款，或者在税收协定中没有加入保留条款的国家，它的cfc立法必定会与税收协定相冲突。
