The Trade in Services Agreement (TiSA) aims to improve global trade in services beyond the limitations of the WTO's General Agreement on Trade in Services (GATS). By analyzing the core text and market access discussions of TiSA negotiations, the focus is on enhancing market access, national treatment, and most favored nation treatment. TiSA also emphasizes high standards for services trade policies through offers and regulatory disciplines. China sees the need to liberalize trade in services to boost its economic development, requiring improvements in the service trade market and domestic regulatory measures.
