During the 2004 Serbian presidential election, Arsić participated in at least one major rally with Radical Party candidate Tomislav Nikolić.
Serbia's electoral system was reformed in 2011, such that parliamentary mandates were awarded in numerical order to candidates on successful lists.
Arsić was quoted as saying, "[Šešelj] could hardly bring the [Radical Party] back to the assembly if he persists with the rhetoric of ten years ago.
[12] He was also appointed as chair of the assembly's committee on finance; in May 2014, he announced that a revised budget by Vučić's administration would introduce low-interest state-subsidized loans.
He attempted to steer a middle course between Russian and European interests, noting that the Serbian delegation "did not support [SEECP's] statement on the crisis in Ukraine, due to the controversial wording about 'annexation of Crimea,' but did not block its adoption either.
"[14] Arsić received the twenty-second position on the Aleksandar Vučić – Serbia Is Winning list in the 2016 parliamentary election and was returned to a seventh term in parliament when the alliance won a second consecutive majority with 131 seats.
He is the leader of Serbia's delegation to the Parliamentary Assembly of the Mediterranean, continues to lead the country's parliamentary friendship group with Greece, and is a member of the friendship groups with Angola, Armenia, Austria, Azerbaijan, Belarus, Bulgaria, Cape Verde, Chile, China, Cuba, Cyprus, the Czech Republic, the Democratic Republic of the Congo, Egypt, Ethiopia, the Gambia, Ghana, India, Japan, Jordan, Kazakhstan, Kenya, Kuwait, Morocco, Nepal, North Korea, North Macedonia, Pakistan, Palestine, Poland, Qatar, Russia, Rwanda, Saudi Arabia, Slovakia, South Africa, Spain, the countries of Sub-Saharan Africa, Switzerland, Syria, Turkey, Venezuela, Vietnam, Zambia, and Zimbabwe.
