# Tariff disputes continue to fluctuate; Alibaba open-sources AI search assistant WebAgent | Review of important news today

## 0530 | **Dolphin Research Key Focus:**

### **🐬 Macro/Industry**

**1、**The U.S. Court of Appeals temporarily reinstated the Trump administration's tariff policy previously halted by the Trade Court, but the final ruling still awaits the Supreme Court (expected to be submitted for debate in June). The White House has stated it will continue to appeal, and the global trade landscape remains uncertain. Meanwhile, Trump's team is already preparing a Plan B.

**2、**After the launch of the HKEX's "Tech Company Hotline," consultation volume surged, with leading companies like CATL and Hengrui Pharmaceuticals planning to list in Hong Kong. At the same time, HKEX and the SFC are advancing the optimization of the listing system, including reviewing the specific requirements for primary, secondary, and dual-primary listings, as well as post-listing regulatory mechanisms. These improvements aim to enhance the overall attractiveness of the Hong Kong stock market.

### **🐬 Stocks**
