What feedback do you have on cross-border commercial dispute resolution?

Specifically - what worked well and what would you do differently? What factors were considered when choosing you method of ADR (e.g., mediation vs. arbitration)? By way of background, I am conducting a research assignment on mediation and seek to focus on commercial mediation in the Asia Pacific region. The intention is to analyse the extent that a country’s 'popular' dispute resolution system influences cross-border disputes. For example, consider whether your organisation refers matters to mediation in Australia but arbitration in other international operations in standard contracts. Why is this? Secondly, I will focus on key trends in Asia Pacific dispute resolution. All feedback/comments are appreciated, and any recommendations for further focus areas. Is there something about international commercial mediation you want to know more about?
