Are these two tables in the same document? If so, what separates them? What separates the country name from any other content that may be in the same cell (e.g. paragraph break, manual line break, tab)?

FWIW, the simplest way would be to merge the two tables into one, sort the merged table, then delete any duplicate rows (e.g. where the country names are the same).
