Chinese enterprises with a global focus are emerging as strong competitors in the international market, especially as they acquire foreign companies or significant stakes within them. Distinct leadership paradigms intersect during interactions or within change processes under Chinese influence, significantly impacting goals, strategies, and actions in areas such as human resource planning, deployment, and development, as well as in communication, gender equality, motivation, and the balance between trust and control. In other words, Chinese businesses are exporting a leadership culture previously unknown in the West. Its ideal follows the large-scale cultural policy of Sinicization, promulgated by state and party leader Xi Jinping. It is rooted in Sino-Marxist values and infused with Confucian, patriotic, and market-oriented elements. This article systematically deciphers the concept of Sinicized leadership for the first time as a leadership ethics paradigm, drawing predominantly on Chinese sources. It sets the stage for meaningful comparison with established alternative schools of thought, which opens a new avenue in foundational research in leadership ethics, with implications that are also of global geopolitical interest.
