# Argentina and Spain press rival territorial claims through formal legal channels

Buenos Aires plans a new Malvinas sanctions law this week; Madrid invokes an 1860 treaty to defend Ceuta and Melilla.

Argentina's government under President Javier Milei announced plans to bring a new sovereignty law before Congress within the week, one that would tighten sanctions on companies operating in the Malvinas Islands without authorization by modifying Law 26.659.[^1]

A continent away, Spanish President Pedro Sánchez told the Congress in Madrid that the 1860 Treaty of Wad-Ras confirms Spanish sovereignty over Ceuta and Melilla.[^2]

The two events share a structure: a government reaching for a legal instrument - one a pending bill, the other a nineteenth-century treaty - to anchor a territorial claim it has held for years. The read here is that both moves are aimed at domestic audiences as much as foreign ones, converting long-standing positions into datable legislative and parliamentary acts. What drove the timing in each capital, the facts do not say.

For Argentina, the legal mechanism is concrete and near-term. A bill modifying an existing law, with stricter commercial penalties, gives Buenos Aires an enforcement tool it can describe in sanctions terms rather than diplomatic ones. Whether Congress will pass it the facts do not say.

Sánchez's argument rests on a document from 1860. Whether his parliamentary audience accepted the reading, or what Morocco's government said in response, the available facts do not carry.
