In Minsk etc., so-so tours a problem for traveller (6,8)

I believe the answer is:

motion sickness

I'm a little stuck... Click here to teach me more about this clue!

'a problem for traveller' is the definition.
I can't judge whether this defines the answer.

'in minsk etc so-so tours' is the wordplay.
'tours' is an anagram indicator (the letters roam or tour around).
'in'+'minsk'+'etc'+'so'+'so'='inminsketcsoso'
'inminsketcsoso' is an anagram of 'MOTION SICKNESS'.

Can you help me to learn more?

(Another definition for motion sickness that I've seen is " It may be suffered when travelling".)

I've seen this clue in The Guardian.
