"It is the first time that we are going to meet and we will discuss a general agreement for judicial cooperation between the two countries," Swedish justice ministry official Cecilia Riddselius told AFP on Friday.
The move comes just two weeks after Swedish prosecutors dropped a sexual assault probe against Assange after the time limit on the case expired, but said they still want to question him about a rape allegation.
Assange has been holed up since 2012 at Ecuador's embassy, which is under 24-hour police guard and close to London's upscale department store Harrods.
