I conduct LPCs on pilots with licences from Sweden, Denmark, Holland and Germany (apart from the majority from UK) and my rights vary. All allow an LPC by a UK JAR TRE, though Germany requires their LPC form to be filled in. Sweden and Denmark allow me to sign the licences, but the others do not, however Sweden won't let me sign a licence after a renewal - only a revalidation. It will be interesting to see how things change - if they do - after next month!
