Xi described this as an “urgent task for advancing high-level openness to the outside world and addressing external risks and challenges”, state news agency Xinhua reported on Tuesday.
He told the gathering of the top decision-making body that creating favourable legal conditions and external environments was essential for the nation’s “rejuvenation” and also concerned the “overall picture of [China] opening up to the outside world and diplomacy”, according to the report.
It comes as Beijing has been trying to expand its legal toolkit on foreign relations – including to respond to sanctions – as rivalry with Washington and its allies intensifies in areas ranging from trade and technology to human rights and geopolitics.
International law expert Huang Huikang delivered a report on the subject at the study session, Xinhua reported, without giving further details.
Huang – who is also a diplomat and a former ambassador to Malaysia – is currently serving a third five-year term as a member of the United Nations International Law Commission.
In his remarks, Xi said China needed to build a “coordinated and efficient” legal system for foreign affairs, that reform was needed in relevant areas of the trial system, and that the credibility of the legal process needed to be improved, according to Xinhua.
He said legal services also needed to be developed, including by cultivating “internationally renowned” arbitration institutions and law firms, and legal professionals that were “politically steadfast and highly skilled” in foreign affairs.
Xi also told Politburo members that China should be proactive by taking part in international rule-setting as part of efforts to position the country as a major power in global governance.
He said a more robust legal framework was needed to safeguard the interests of overseas Chinese, including through more international cooperation and stronger consular protection, according to the report. Xi also called for measures to improve convenience for foreigners living in China.
Beijing has brought in more foreign policy legislation in recent years in response to a more challenging international environment.
A new Foreign Relations Law also took effect in July, with a focus on national security and countering the alleged “long-arm jurisdiction” of the US and other nations. It is another effort to back Beijing’s response to sanctions imposed by the West.
