将以下文本翻译成英文：约无效、暂停实施和条约终止是国际条约法中三个重要的概念它们之间的比较如下：1 条约无效指的是条约在签订或生效后被认为是无效的。条约无效可以分为绝对无效和相对无效两种情况。绝对无效是指条约的内容违反国际法的强制规定例如违反联合国宪章的条款违反人权保护原则等这种情况下条约被视为从未存在过。相对无效是指条约在签订时存在缺陷或者违反了当事国的国内法规定这种情况下条约对当事国之间的关系

Invalidity, suspension of implementation, and termination of treaties are three important concepts in international treaty law, and their comparisons are as follows:

1. Invalidity of treaties

Refers to a treaty being considered invalid after it is signed or comes into effect. The invalidity of a treaty can be divided into two types: absolute invalidity and relative invalidity. Absolute invalidity refers to the content of a treaty violating mandatory provisions of international law, such as violating provisions of the United Nations Charter or human rights protection principles. In this case, the treaty is considered to have never existed. Relative invalidity refers to a defect or violation of domestic law provisions of a party to the treaty at the time of signing. In this case, the treaty is invalid for the relationship between the parties to the treaty.

2. Suspension of implementation

Refers to some or all of the provisions of a treaty temporarily losing effectiveness for a certain period of time. In this case, the parties to the treaty suspend the implementation of the treaty provisions, but the treaty is not abolished or terminated. The suspension of implementation is usually decided by the parties through consultation or by a ruling of an international court or arbitration institution.

3. Termination of treaties

Refers to all the provisions of a treaty ceasing to be effective after a certain period or under certain circumstances. The termination of a treaty can be divided into two types: automatic termination and negotiated termination. Automatic termination refers to the treaty automatically ending when the time specified in the treaty expires or certain conditions specified in the treaty are met. Negotiated termination refers to the parties to the treaty reaching a consensus through consultation to terminate all or some provisions of the treaty. After the termination of the treaty, the parties are no longer bound by the treaty, but actions taken before the termination are still effective.

Invalidity, suspension of implementation, and termination of treaties are different legal consequences in international law, and their main differences lie in their effectiveness and scope of influence.

1. Invalidity of treaties:

The invalidity of a treaty refers to the existence of illegality or defects in the signing or approval of the treaty by one or more of the contracting parties, which makes the treaty unable to have legal effect. These illegality or defects include but are not limited to: failure of one or more of the contracting parties to fulfill its domestic legal procedures, lack of necessary authorization, inconsistency with international public order, etc. The invalidity of a treaty means that the treaty never existed, and is invalid and illegal.

2. Suspension of implementation:

The suspension of implementation refers to one or more of the contracting parties temporarily suspending the performance of some or all of the contents of the treaty during the validity period of the treaty. The suspension of implementation is usually due to temporary, special, or unforeseen circumstances or events, such as war, natural disasters, etc. The suspension of implementation does not change the legal effect of the treaty, but only temporarily interrupts the obligation to perform. When the temporary situation disappears, the contracting parties should resume performance.

3. Termination of treaties:

The termination of a treaty refers to one or more of the contracting parties deciding to terminate the effectiveness of the treaty through a lawful procedure, so that the treaty no longer has any legal effect. The termination of a treaty usually occurs when the treaty's validity period ends, the contracting parties agree to terminate, one or more of the contracting parties violate the treaty, etc. After the termination of the treaty, the contracting parties are no longer bound by any performance obligations, and the content of the treaty no longer has legal effect
