In June 2009, Belarussian broadcaster National State Television and Radio Company of the Republic of Belarus (BRTC) won the rights to organise the contest over bids from Russia and Malta.

[4] EBU initially put efforts into distributing the organisation of the contest among different regions of the continent, moving away from Eastern Europe as Kyiv hosted the previous edition, with Malta's bid seemingly taking the lead.

However, BRTC's detailed candidacy supported by Eurovision Song Contest 2009 winner Alexander Rybak prevailed in the end.

"[3] Despite originally estimating the number of participants to be between 20 and 25,[4] on 28 July 2010 it was announced 14 countries would compete in the contest, with Moldova making its début and Latvia and Lithuania returning.

[8] Prior to the event, a digital compilation album featuring all the songs from the 2010 contest, along with karaoke versions, was put together by the European Broadcasting Union and released by Universal Music Group on 19 November 2010.

[14] Theme art was also incorporated in the promotional billboards and posters featuring 11 "faces of Junior Eurovision" selected through casting procedure.

Results of castings were revealed on 20 July 2010 and the 11 chosen ones were Belarus TV personalities Denis Kourian, Olga Barabanschikova, Irina Kazantseva, Andrey Bibikov, former JESC entrants Alexey Zhigalkovich, Ksenia Sitnik, Yuriy Demidovich, Alina Molosh, Daria Nadina as well as non-professionals Yulia Brazhinskaya and Ilya Ilmursky.
