The Possible Entente Zone (ZOPA) is the area of a negotiation where two or more parties can find common ground. Here, the negotiating parties can work towards a common goal and reach a possible agreement that incorporates at least some of the other`s ideas. ZOPA is sometimes referred to as a “trading area” or a “trading area”. There are or have been plans for lithuania-Russia, Poland-Belarus, Bulgaria-Serbia and Bulgaria-North Macedonia local transport agreements.  The agreement between Poland and Belarus was due to enter into force in 2012, but was delayed by Belarus with no fixed implementation date (october 2012).  “Russia will certainly take the necessary precautions to ensure that the Idlib de-escalation zone is not attacked. Together, we will ensure the detection and prevention of third-party provocations and breaches of contract. A negative trading area can be overcome by “widening the pie.” In inclusive negotiations on a variety of issues and interests, parties who combine their interests to create value come to a much more rewarding agreement. Behind each position, there are usually more common interests than contradictory.  Licences are issued with a validity period of between one and five years and allow a stay in the border area of up to three months. Permits can only be granted to legitimate residents of the border area who have settled in the border area for at least one year (or more if specified in the bilateral agreement). Permit applicants must demonstrate that they have legitimate reasons for frequently crossing an external land border under the local border traffic regime.
The Schengen States must keep a central register of authorisations granted and grant the other Schengen States immediate access to the relevant data. Vatican City has an open border with Italy. In 2006, it expressed its interest in joining the Schengen Agreement with a view to closer cooperation on the exchange of information and similar activities covered by the Schengen Information System.  Exceptionally, Italy allowed people to visit Vatican City without being accepted for an Italian visa, and then escorted by police between the airport and the Vatican or using a helicopter. [Citation required] However, there is no customs union (including customs duties) between Italy and the Vatican, so all vehicles are checked at the Vaticano borders. .
