《舊金山和約》第26條:「...... Should Japan make a peace settlement or war claims settlement with any State granting that State greater advantages than those provided by the present Treaty, those same advantages shall be extended to the parties to the present Treaty.」意即:如果日本跟沒簽《舊金山和約》的盟國成員簽約,條件優於《舊金山和約》的話,其他盟國成員全都可以一體適用。
