The tariffs imposed by the US on China are having a significant impact on the Chinese economy.
While I don't have real-time data, I can tell you that tariffs can lead to increased costs for Chinese exporters, potentially reducing their competitiveness in the global market.
This could result in decreased exports, economic slowdown, and possible decline in certain sectors. However, China's economy is complex and has many factors at play, so it's difficult to make a definitive statement about its overall decline.
It's also worth noting that the exact tariff rate you mentioned, 245%, seems unusually high and may not be accurate. Typical tariff rates are much lower, usually in the range of 10-30%.
For the most up-to-date and accurate information, I recommend checking reputable news sources or economic reports.
