The European Union (EU) is said to be seeking to abolish the phutia of member states to ensure the bloc's foreign policy is not interrupted, especially support for Ukraine and sanctions against Russia.
Slovakia and Central European neighbor Hungary have long opposed the EU's approach to the conflict in Ukraine, criticizing military aid to Kiev and sanctions against Russia.
Both governments have repeatedly threatened to use their boycott to stop the EUs actions, which they say harms national interests.
To overcome this disagreement, Brussels is said to be considering a shift from absolute majority voting - a fundamental principle in the EU's foreign policy - to the form of "qualified majority".
The new form is expected to help the decision-making process become more efficient and avoid being paralyzed by a few individual countries in common action.
However, this move was strongly condemned by Slovakian Prime Minister Robert Fico.
Speaking at the Conservative Political Action Conference (CPAC) in Hungary, Mr. Fico affirmed that once the idea of blocking the right of refusal becomes a reality, all common projects in Europe will collapse.
According to the Slovakian Prime Minister, this move is no different from "putting up a new iron curtain" to promote war rather than peace. This is a sign of a major military conflict coming, Fico warned.
Hungarian Prime Minister Viktor Orban also has a similar view.
Mr. Orban said that abolishing the right to vote would take away the sovereignty of smaller countries.
We want Brussels to show respect for us as for other member states, not only in name but also in real terms, which is in our interests, the Hungarian Prime Minister said last month.
Both Slovakia and Hungary have opposed increasing military assistance to Kiev, in which Hungary has blocked several key decisions due to concerns about national interests and the risk of escalating the conflict.
