In the issue of tariffs, why did the US and Japan fail to reach an agreement again?

Japan is an important ally of the United States in the Asia-Pacific region, however, the tariff policies introduced by the Trump administration did not give Japan "special treatment", which has led to strong opposition from Japan. Although the two sides have conducted two rounds of negotiations, consensus has not yet been reached. So what information can be interpreted from the latest statements of the US and Japan? Special commentator Su Xiaohui said: Faced with the US's continuous pressure, Japan is now struggling to cope and is also worried about its own situation. Because when it comes to the automotive industry, Japan has no room to back down. The automotive industry is an important employment sector in Japan, with about 8% of the total workforce employed in the industry, which is crucial for the Japanese government's governance. If Japan continues to compromise and retreat, it will cause severe domestic turmoil and directly affect the ruling Liberal Democratic Party. At the same time, we see that Japan has put forward conditions, hoping to exchange the review of non-tariff barriers and increased imports of American agricultural products in exchange for exemptions from the US. However, when Japan made these conditions, the US ignored them and continued to escalate. So at this point, Japan has shown a reactive response and has suggested that it may use huge amounts of US debt as a bargaining chip to negotiate with the US, issuing a warning to the US. If the US continues to press on in the tariff war, both sides will ultimately suffer.
