Iohannis took office on 21 December 2014, when Traian Băsescu 's term ended. His presidential campaign focused on fighting corruption and on improving the justice system. Iohannis is also a supporter of a strongly pro-Western foreign policy. Regarding the unification of the Republic of Moldova with Romania, much discussed in the electoral campaign, Iohannis stated that "is something that only Bucharest can offer and only Chișinău can accept", and this "special relationship must be cultivated and enhanced especially by us [the Romanian state]". Upon taking office, Iohannis suspended his membership within the National Liberal Party (PNL); the Romanian constitution does not allow the president to be a formal member of a political party during his tenure.
