Xue Hanqin has just been elected to the International Court of Justice. You can find some glimpses of her views in a 2006 article: vaguely supportive of the ICC, not a fan of universal jurisdiction. Relevant section on UJ below:
At the moment, one of the most controversial issues with international criminal law is the question of universal jurisdiction. Under traditional international law, states establish universal jurisdiction over certain international crimes by treaty terms except for one case, piracy. In other words, regardless of general jurisdictional grounds on territory, nationality, protection and so on, states establish national criminal jurisdiction over certain offences simply by the physical presence of the alleged suspect. In exercising such criminal jurisdiction, not only judicial assistance is assured between the state parties under the relevant treaty, rules of sovereign immunity are also respected under general international law. The early conventions on human rights are vague on the point, but state practice and international court decisions support this position. In the Pinochet case, although the British House of Lords declined to embrace one Lord's opinion grounding extradition on international custom regarding universal jurisdiction, its ruling did affect the doctrine of Act of State as practiced in the past. By pronouncing what constitutes or does not constitute an act of state of another state, or by national legislation to establish absolute universal jurisdiction, national courts would likely exercise jurisdiction over cases that may lead to international disputes by unduly encroaching upon the domestic affairs of other states. So far state practice shows over-extended national jurisdiction, either civil or criminal, is not conducive to promoting international efforts in suppressing international crimes, nor to maintaining international peace and stability.
