September 11, 2013 finishing the talks between between H.E. Yaroslav Mar, President of the Federal Republic of Lostisland and H.E. Jeffrey Araya, President of the Republic of Jax, a micronation based in Costa Rica, was signed the Agreement on Entering of the Republic of Jax into the Federal Republic of Lostisland.
According to the Agreement, the Republic of Jax, with all her resources and territories, becomes a Federation (Federal Subject) of a single and indivisible state – the Federal Republic of Lostisland, and is renamed into the Federation of Jax, passing under the jurisdiction of the Federal Republic of Lostisland (as an integral state) the matters of establishing general rules and legislation, diplomacy and international relations, defense, national security, law and order, management of the judicial and banking systems. Lostisland, in her turn, accepts Spanish as one of the co-official languages of the Federal Republic (alongside with English, Dutch, Turkish and Russian).
It is thought that Mr Araya, apart from managing the region, will be in charge for strengethening Lostislandic positions and influence in the Caribbean region, in particular, by promoting Lostisland amongst other micronations of the sector. The admission of Jax is the third expansion of Lostisland in 2013, after Antarcsas and Pavlov (transition into the Federal Republic).
