Since 1989, the Middle Eastern country Saudi Arabia suddenly announced the severance of all diplomatic relations with the Southeast Asian country Thailand.
The diplomatic level between the two parties was directly downgraded from ambassador to chargé d'affaires.
Of the 250,000 Thais working in Saudi Arabia, except for a few thousand who were given special exemption, the rest were all expelled from Saudi Arabia.
Besides that, Saudi Arabia also withdrew all its investments in Thailand and issued a ban on tourism to Thailand within the country.
Honestly speaking, reaching this point, the relationship between the two countries was basically no different from a declaration of war.
The reason they didn't actually fight is mainly because the two countries do not share a border and are significantly distant from each other; even engaging in a naval battle would require passing through several countries.
The cause of this outcome was due to a blue diamond.
