The third round of Sino-US trade negotiations took place in Sweden, and neither side released a joint press statement nor signed an agreement. Chinese official media reported that both sides will push for the extension of the 24% tariff imposed by the US and China's countermeasures for 90 days. US Treasury Secretary Yellen stated that whether the extension will take place depends on Trump's decision. Currently, Trump has not made a final decision and may be waiting for the outcome of the US-Russia negotiations on the Ukraine issue. If the US and Russia fail to reach an agreement, the US may impose secondary sanctions on countries such as China and India, i.e., an additional 25% tariff. The US has already imposed an extra 25% tariff on India's purchase of Russian oil. After the US special envoy visited Moscow, the leaders of the US and Russia will meet, which may affect the US's decision on sanctions against China and India. During the Geneva talks in May, China and the US agreed to remove unreasonable tariffs, but if Trump re-imposes tariffs on China and adds secondary sanctions on August 12, the Sino-US trade war will reignite. Analysts believe that Trump may launch another tariff war against China after his allies reach an agreement, in order to promote the resolution of the Ukraine issue. Currently, the Sino-US tariff negotiations have not reached a clear conclusion, and the key lies in Trump's interaction with Putin. If the US-Russia negotiations are successful, the Sino-US tariff extension may be prolonged; if the negotiations fail, the Sino-US tariff war may reignite. The Taiwan issue may also become Trump's 'sticking point,' and the Solomon Islands may propose to exclude China and the US from participating in the Pacific Islands Forum. Trump's global reciprocal tariff strategy has hit a snag in China, and the Sino-US trade war is far from over. The competition between major powers requires repeated negotiations to find the real ceasefire line.
