Asia-Pacific markets were poised to open mixed as investors assessed the Shanghai Cooperation Organization meeting of leaders in Tianjin, with tariff uncertainty weighing on sentiment.

This comes after a U.S. federal appeals court on Friday ruled that most of President Donald Trump’s global tariffs are illegal.

Japan’s Nikkei 225 was set to open higher, with the futures contract in Chicago at 42,310, while its counterpart in Osaka last traded at 42,400, against the index’s Monday close of 42,188.79.

Australia’s S&P/ASX 200 was set to start the day lower, with futures tied to the benchmark at 8,886, compared with the index’s last close of 8,927.70.

The country’s current account balance for the April to June quarter is expected later in the day. Economists polled by Reuters expect a deficit of 16 billion Australian dollars ($10.49 billion), compared to the AU$14.7 billion deficit the quarter before.
