Fresh Exclusive / Analysis: Cambodia and Thailand Are Unequal in Power: What Opportunities Does UNCLOS Offer Cambodia?

Fresh NewsFresh News AsiaFresh News

The Fresh News analysis argues that compulsory conciliation under UNCLOS does not equalise the two states’ military or economic power but provides a framework for presenting evidence, maps, technical data and legal arguments to an independent commission. It also states that the process guarantees neither a Cambodian victory nor a binding judgment and requires the commission to examine both governments’ positions while assisting them in seeking agreement.
