Reference to any of a creditor's acts mentioned in sub-paragraphs (a) and (b) of paragraph (1) barring the effect of any enactment or rule of law relating to the limitation of actions is to be construed as a reference to that act having the same effect, for the purposes of that enactment or rule of law, as an effective acknowledgement of the creditor's claim.

Reference in paragraph (1) or (2) to an enactment does not include a reference to an enactment which implements or gives effect to any international agreement or obligation.
