#TradeWarEases means that a trade dispute (a "trade war") is diminishing, being resolved, or having a pause. It may mean that tensions between countries are decreasing, with fewer tariffs or other protectionist measures being applied.

Elaboration:

In terms of international trade, "trade war" refers to a period of trade tensions between countries, usually characterized by high tariffs or other protectionist measures. When the situation "eases", it means that aggressive measures are being reduced or suspended, whether through negotiations, trade agreements, or other types of resolution.
