Balogh said that the government's efforts to seek closer ties with Hungarians in neighbouring countries and re-unite the nation should also involve reducing differences within the country's borders.
The Socialist Party finds it unacceptable that the government should differentiate between ethnic Hungarian organisations and grant more benefits to one than to others, said Balogh.
As for voting rights, Balogh said that those rights should be granted with respect to residence and participation in bearing the pubic burden. He added that rolling out electoral rights to ethnic Hungarian communities would generate political tension, which could harm ethnic kin.
On Wednesday, Deputy Prime Minister Zsolt Semjen addressed a youth camp for Hungarians in Tusnadfurdo, Romania, and said that the purpose of Hungary's dual citizenship law, adopted last year, was to help ethnic Hungarians fight the threat of assimilation.
More than 120,000 applications have been filed and 20,000 people have been granted citizenship so far, he said.
