The Republic of Cyprus also allows passage across the Green Line from the part of Nicosia that it controls, as well as a few other selected crossing points, since TRNC does not leave entry stamps in the passport for such visits. Since May 2004 some tourists have taken to flying to the Republic of Cyprus directly then crossing the green line to holiday in northern Cyprus. Northern Cyprus is legally part of the EU, but law is suspended due to north being under the control of the Turkish Republic of Northern Cyprus, which the EU does not recognise. The North uses the Turkish lira instead of the euro, although the euro circulates alongside the lira and other currencies. On the resolution of the Cyprus dispute and the reunification of the island, the euro would become the official currency of the north also. Adoption by the North would be the first time the euro has replaced use of another currency that hasn't ceased to exist after euro adoption. Euro adoption would help to address inflation in the North by bringing in price stability. Cypriot euro coins already bear the name of Cyprus in both Greek and Turkish, displaying representations of natural and ancient Cypriot history. In wake of the April 2004 referendum on unification, and the support of the Turkish Cypriot community for the plan, the European Union made pledges towards ending the isolation of northern Cyprus. The proposal for trade between the EU and the Turkish Cypriots was never implemented due to opposition from the Greek Cypriots, who argue that trade would amount to indirect recognition of the TRNC. Proposals to open up trade were discussed by Parliament again in 2010, but still opposed by the Republic of Cyprus. The EU has helped the Turkish Cypriot community prepare to implement EU law in the future, as a final reunification settlement would mean the application of EU law throughout Cyprus. Through the Financial Aid Regulation, the EU has funded infrastructure projects, civil society and has provided training on the EU body of laws. To manage the interaction with the EU, the Turkish Cypriots have introduced a series of institutions, such as the EU Coordination office. The Green Line Regulation has been implemented to regulate movement through the 'Green Line', the border that separates Greek Cypriot and Turkish Cypriot areas, and to help the economic development of the Turkish Cypriots. In order to avoid recognising the TRNC by implication, The European Commission has dealt with the Turkish Cypriot Chamber of Commerce rather than ministerial authorities, which would have been the norm. This offered the chamber an important role in the relations with the EU.
