外交行动

采取外交行动是一个国家进行外交的重要手段，例如改善/破坏关系、签署各种协议。外交行动是由一国发起的目标为另一国的互动，有些外交行动需要目标国的同意才能生效。

外交行动类型

所有的外交行动可被分为三种类型：

• 即时行动：这类外交行动将会在目标国同意之后立刻生效（如果需要同意的话）。因为其是即时完成的，因此该类别的行动不需要任何影响力来维护。
• 持续性行动：这类外交行动是发起国对目标国的持续性行动，且只能由发起国取消。由于其持续性，此类行动的发起国需要消耗影响力来维持其外交行动，行动的目标国则不需付出任何影响力。
• 条约：这类行动指那些只要双方同意就可持续维持下去的各种协议。如果需要影响力进行维护，则双方都需要支付其影响力，除非该条约规定了明确的主从关系（如宗主国需要付出影响力维持与其附属国的附属关系）。条约的双方均可取消此项条约，但往往需要另一方的统一。

开展外交行动的条件纷繁复杂，开展不同的行动往往需要先满足各种前提条件。

即时行动

Some example actions in this category are:

• Expel Diplomats: This is an action that immediately lowers Relations with the target country, stops any ongoing attempt by them to Improve Relations with you, and blocks further Improve Relations attempts for a period of 5 years. Using Expel Diplomats also gives the acting country some Infamy, and prevents them from using Expel Diplomats on the same country for 5 years.
• Take on Debt: This is an action that allows one country to take on the debt of another in exchange for being owed an Obligation (more on this in later dev diaries).
• Absolve Obligation: This is an action that forgives an Obligation owed to the acting country in exchange for a large boost in Relations.
• Violate Sovereignty: This is an action that allows the acting country to violate the neutrality of another country through whom they need military access, creating a Diplomatic Incident and potentially bringing new countries into the conflict. We'll go more into under what conditions you can use this and exactly how it works at a later time.

持续性行动

Some example actions in this category are:

• Improve Relations: This is an ongoing action that slowly raises relations up to a maximum value of 50 (out of 100). Costs Influence to maintain, with the cost increasing if the target has a high Rank
• Damage Relations: This is an ongoing action that slowly lowers relations down to a minimum value of -50 (out of -100). Costs Influence to maintain, with the cost increasing if the target has a high Rank
• Bankroll: This is an ongoing action where one country pays a part of its monetary income to another each week as direct subsidies to their state treasury.

条约

Some example actions in these categories are:

Non-Subject Pacts

• Alliance: This is a diplomatic pact that allows two countries to help each other when attacked in a Diplomatic Play, even if they do not have an Interest in the relevant area (more on this next week). Costs Influence to maintain, with the cost increasing if the other part has a high Rank.
• Customs Union: This is a diplomatic pact where there is a senior and a junior partner, and makes the junior partner part of the senior partner's national market instead of having their own market. Costs Influence to maintain for the senior partner only, with the cost increasing if the other part has a high Rank.
• Trade Agreement: This is a diplomatic pact which gives both countries competitive advantages when establishing trade routes in the market of the other country. Costs Influence to maintain, with the cost increasing if the other part has a high Rank.

Subject Pacts

• Protectorate: This is a type of non-colonial subject relationship where the subject is very autonomous, the only restriction placed on them being that they are not able to have a fully independent foreign policy. Can be turned into a Puppet by their overlord through a Diplomatic Play.
• Puppet: This is a type of non-colonial subject relationship where the subject has no diplomatic autonomy, pays part of their income to their overlord and is part of the overlord's national market. Can be annexed by their overlord through a Diplomatic Play.
• Dominion: This is a type of colonial subject relationship where the subject has extensive diplomatic autonomy and can have their own subjects, though they're still required to be part of their overlord's market. Can be turned into a Territory by their overlord through a Diplomatic Play.
• Territory: This is a type of colonial subject relationship where the subject has limited diplomatic autonomy, pays part of their income to their overlord and is part of the overlord's national market. Can be annexed by their overlord through a Diplomatic Play.
• Tributary: This is a special subject relationship only available to Unrecognized Powers where the subject has extensive diplomatic autonomy and can have their own subjects, though they're required to pay part of their income to their overlord. Can be turned into a Vassal by their overlord through a Diplomatic Play.
• Vassal: This is a special subject relationship only available to Unrecognized Powers where the subject has no diplomatic autonomy, pays part of their income to their overlord and is part of the overlord's national market. Can be annexed by their overlord through a Diplomatic Play.
