外交机制包含三个基本要素：关系、恶名与利益。

== 关系 ==
关系是一个介于 {{red|-100}}与 {{green|+100}}之间，展现两个国家宏观外交立场的数值。维多利亚3中的外交关系系统是双向的，即两个国家的外交关系总是由一个数值衡量，而非其他游戏中单向关系。这一系统清楚地衡量了两国对对方的外交立场，这一机制性效果将同时作用于AI和玩家（即使是在多人游戏中）。

所有外交关系数值将会转换为一个关系等级，达到不同等级所需的数值列在下表（从高到低）：

* [[File:Relations friendly.png|32px]] {{green|亲密}} ('''80''' - '''100''')
* [[File:Relations amicable.png|32px]] {{green|善意}} ('''50''' - '''79''')
* [[File:Relations cordial.png|32px]] {{green|合作}} ('''20''' - '''49''')
* [[File:Relations neutral.png|32px]] 中立 ('''-19''' - '''19''')
* [[File:Relations poor.png|32px]] {{red|较差}} ('''-20''' - '''-49''')
* [[File:Relations cold.png|32px]] {{red|冷漠}} ('''-50''' - '''-79''')
* [[File:Relations hostile.png|32px]] {{red|敌对}} ('''-80''' - '''-100''')


=== 外交关系的作用 ===
外交关系等级将会影响AI是否接受外交提议以及在[[外交博弈]]中支持哪一方。此外，达到不同外交等级也将允许/禁止对该国家发起特定外交行动。

例如，达到 {{green|合作}}或以上的外交关系等级后将禁止两国对对方发起绝大部分的外交博弈，几乎可被视为一种互不侵犯条约。同时，邀请他国进入关税同盟也需要两国关系等级至少达到合作。另一方面，进行特定敌对外交行动，如禁运、宣告宿敌等则需要两国关系低于特定等级。

=== 改变关系等级 ===
The primary way to change relations is through the Improve relations and Damage relations ongoing diplomatic actions, but there's many other ways in which relations can be increased or decreased, including various events, diplomatic incidents and the Expel Diplomats diplomatic action, which is a way in which one country can act to prevent another from cozying up to them relations-wise, though at the cost of gaining infamy.

== 恶名 ==
A country has an infamy value that starts at 0, and which may increase up to 1000. As a country's infamy increases, other countries will become more wary, resulting in various diplomatic penalties for the infamous country. If infamy exceeds the pariah threshold (which is currently set to 100) the country becomes a potential target for a special "contain threat" diplomatic play where the great powers step in to "restore order". 
Infamy decays slowly over time, and its rate of decay can be increased if the country has a large amount of unallocated Influence capacity, representing that capacity being put to use trying to salvage the country's global reputation instead.

Infamy in itself should be understood as a measure of how concerned the great powers are about a country, and as such, country rank has an effect on how much infamy a country gets when it commits a diplomatic transgression against another. Generally speaking, the lower the rank of the two countries involved, the less infamy will be generated, as the great powers care a lot more about actions taken by and against other great powers than they do over two minor powers being engaged in a local squabble.

Ultimately, what this means is that infamy doesn't just have a global effect, and where you're accruing it matters. If you keep taking actions that destabilize a particular strategic region, you can expect to quickly become very unpopular with both the locals and any outside powers that have taken an interest in it.

=== 外交事件 ===
Infamy is tied to the diplomatic incident mechanic. In the vast majority of cases, any action a country takes (for example demanding land in a diplomatic play or violating a neutral country's sovereignty during war) that increases infamy will also create a diplomatic incident localized at a particular strategic region on the map.

For example, starting a diplomatic play to demand a colony in West Africa will result in a diplomatic incident occurring there. Whenever a diplomatic incident happens, the country that caused it immediately suffers a penalty to their relations with all countries that have an interest in the region, with the amount of relations lost based on the amount of infamy attached to the Incident in question.

=== 恶名等级 ===
<!-- [to update] -->

0 to 24,9 - Reputable

25 to 49.9 - Infamous

50 to 100 - Notorious

>100 - Pariah

== 利益 ==
Interests is a mechanic that determines whether or not a country has a stake in a particular strategic region and plays into numerous different mechanics such as diplomatic plays, colonization and the aforementioned diplomatic incidents. 

Interests do not provide any inherent benefit to a country besides the ability to throw their weight around in a strategic region, and can actually be a bit of a double-edged sword in that a country with interests all over the world may get dragged into a lot of local conflicts. Ultimately, interests are intended to simulate such historical occurrences as why certain parts of the world simply got a lot more attention from the great powers than others at particular points during the century that Victoria 3 covers, and to make nations act and care about things in a way that makes sense according to their national self-interest.

A country can gain an interest in a region in one of two ways: either automatically by having a geographical presence there (owning land or controlling subject nations in the region) or by using a declared interest.

=== 宣告利益 ===
A declared interest is a country quite simply saying that, regardless of their lack of a geographic presence, a strategic region is still of importance to them, perhaps because they plan to colonize it, or because they want to prevent a hated rival from expanding into it. A country can declare an interest in any region that is either adjacent to a region where they already have an interest, or which they can reach through the support of their naval supply network. The number of declared interests that is available to a country depends on their rank - a great power can choose to have its fingers in a great many pies, while an insignificant power is limited to acting only in regions where they already have land.

=== 可宣告利益数量 ===
A country may declare as many interests as its Maximum Declared Interests cap. This cap is determined by [[Rank|ranking]], and the presence of [[List of buildings#Naval Base|Naval Bases]] in the country.
