Besides, optimism rose after Chinese data showed a sharp rebound in crude imports in March. China's crude oil imports in March were up nearly 5 percent from a year earlier, boosted by Iranian oil and a rebound in Russian deliveries. Meanwhile, geopolitical tension intensified in Europe after Russia conducted missile attack on the northern Ukrainian city of Sumy.
