London (CNN Business) 1. Trade war: The worsening trade war between the United States and China is causing fresh pain for investors in Asia, but other global markets are looking brighter.

Europe started positively, with London's FTSE 100 index 0.7% higher and Germany's DAX index up 0.3% as trade fears appeared to fade.

US stock futures are also pointing to gains, with the Dow set to rise about 100 points when US markets open Tuesday. The Nasdaq is tracking a 0.7% rise, and the S&P 500 could jump 0.5%.

That follows a dismal Monday, when the Dow closed 617 points, or 2.4%, lower. The S&P 500 closed down 2.4% and the Nasdaq lost 3.4%.

Stocks were pummeled by China's announcement that it will increase tariffs on roughly $60 billion worth of US goods on June 1, retaliating against higher tariffs imposed by the Trump administration last week.

The situation could still deteriorate further. The Trump administration has begun the process to apply tariffs of 25% to the remaining $300 billion worth of goods China exports to the United States.
