U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the white cement will also increase.

The coronavirus (COVID-19) pandemic not only had a significant impact on public health, it also severely affected one of the linchpins of the global economy – the tourism industry. As many countries introduced curfews and travel restrictions to contain the spread of the virus, travel across the world significantly declined from early 2020 onwards. The financial repercussions of the coronavirus have already begun to manifest themselves within the tourism industry.
