the map at the end of this official but as yet unratified treaty
http://russia.shaps.hawaii.edu/fp/us/agree.html
gives west longitude 168deg 58min 37sec as wet rue
aka the easternmost extremity of russian territorial waters
but it is based on a fully ratified 1867 treaty
so i presume it is correct & effective
that is absolute rue too
& dry rue
aka the easternmost point of dry land in russia
is about 1500 meters west of that
on the easternmost point of big diomede island
but i could only approximate the longitude for that
if you still want it anyway
& please see 1 insert below

again a distinction could be made between wet & dry
the easternmost & westernmost points of the usa actually
converge further
if you mean to include the american territorial waters
&or the american eezs
technically the easternmost & westernmost points of the usa are
both at 180 longitude
just like the dry east & west russia extremes you mention below
