Tokyo: The greenback clawed back losses as China and Japan reopened following holidays. The dollar index, which measures the greenback against a basket of currencies, rallied 0.2 percent to 97.90. The yen dipped after China announced export controls on Japanese companies in a further sign of souring relations.

According to Qatar News Agency, the euro slid 0.14 percent to $1.1768, while the yen sank 0.4 percent to 155.27 per dollar. The sterling pound fell 0.08 percent to $1.3478. Meanwhile, the Australian dollar strengthened 0.1 percent versus the greenback to $0.706, and New Zealand's kiwi was little changed at $0.5957.

China's yuan hit the strongest level against the dollar in nearly three years on hopes that Trump's new tariff regime would lower taxes on Chinese exports.
