What country shares a border with non speaking country?

Answer 1

tho no country is entirely non speaking

all countries are at least partly non speaking

insofar as they all have underwater parts & libraries & deaf mutes etc

so all countries that have any borders at all must share them with non speaking countries

to that extent

the only countries that

d o n t

share borders with any countries

& therefore with any non speaking countries

are island countries lying more than 24 nautical miles from the nearest other countries at low tide

say Barbados or Iceland or tuvalu etc

so long as you understand that these are not examples that answer the question

but rather only a few of the rare examples that do not answer the question

an example from among the many dozens & scores & indeed hundreds that do answer the question might be

the united states

wherever Mexico or Canada are considered non speaking country

as for example on the seabed just off their Atlantic or pacific coasts

indeed these parts of the American borders might even be called their non speaking parts

but not out loud right there
