With Donald Trump returning to the White House, the United States has once again adopted a strong protectionist approach. High tariffs targeting Chinese products are once again drawing attention from the international community, just like they did during his first term. In response, China is taking active countermeasures. The conflict between the two countries is no longer limited to simple trade disputes as it spreads into the realm of political tension and begins to reshape the global order. President Trump has revived the "America First" agenda and reintroduced steep tariffs on Chinese imports. He accuses China of providing unfair subsidies to its domestic companies and violating intellectual property rights. To stop this, the U.S. is imposing high tariffs on key sectors such as electronics, steel, and semiconductors. Although American consumers are experiencing price increases, the Trump administration sees long-term industrial protection as more important than short-term economic pain. China is not staying quiet. It has imposed counter-tariffs on U.S. goods and is accelerating efforts to reduce its reliance on foreign trade. One of its key moves is restricting the export of rare earth elements, which are vital to U.S. industries. At the same time, China is pushing for domestic consumption and investing heavily in technological self-reliance, especially in sectors like semiconductors. China is also strengthening ties with developing regions such as the Middle East and Latin America to diversify its economic partnerships. Through the Belt and Road Initiative—a global infrastructure and trade strategy—China is building economic links across Asia, Europe, and Africa to create a China-centered trade network. These efforts reflect a broader strategy: avoiding confrontation with the U.S. while steadily expanding its global influence. This growing tension is now spreading beyond the economy to politics and diplomacy. The U.S. is asking its major allies to join in keeping China in check, and some countries are going along with it. Others, however, are showing a cautious attitude to strike a balance between the two countries. The European Union, for example, began to seek autonomy while distancing itself from the U.S. Meanwhile, Southeast Asian countries are acting carefully, mindful of their close economic ties with China. Many in the international community are concerned that the prolonged U.S.-China conflict could affect global supply chains, investment flows, and even security. The renewed U.S.-China trade war under President Trump is no longer just about economics. Now, it has become a geopolitical struggle over global leadership. Currently, the conflict shows no signs of resolution and, instead, grows into a more complex international situation. How this trade war unfolds will serve as a major indicator of the future direction of global order. In this new reality, countries around the world must rethink their strategies to safeguard their national interests.
