The inspections have been a challenge for the shipping companies

The Finnish government has voiced concern over surprise inspections on Finnish cargo ships visiting Russian ports in recent weeks, saying delays had been a problem for shipping companies.

Neighboring Russia carried out seven thorough inspections in the past two weeks on Finnish ships at St Petersburg and other ports, without giving a specific reason, a government minister said on Friday.

Such inspections usually take place for Finnish ships only a few times a year globally.

“The inspections have been exceptional ... It is a challenge for the shipping companies, it makes their operation more difficult,” Minister of Transport and Communications Anne Berner told Reuters.

“There have been inspections by Russian ports for ships from other countries as well, but in this time range, most of the inspections have been carried out on Finnish ships.”

The Russian transportation ministry declined to comment but Berner said that seafaring authorities from the two countries had held discussions, with talks due to continue next week.
