Two data cables running across the land border between Sweden and Finland have been repaired, a day after they were damaged affecting 6,000 private customers and 100 businesses, a company providing digital infrastructure and data communication in Northern Europe said Tuesday.

Two inland fiber optic cables between Sweden and Finland have been cut, with one being damaged during construction.

Sweden has formally asked China to co-operate with an investigation into damage to two cables in the Baltic Sea last month. The cables - one linking Sweden to Lithuania and the other between Finland and Germany - were damaged in Swedish territorial waters in the Baltic Sea on 17 and 18 November.
