China on Monday denounced countries that are practicing "appeasement" with the United States in trade negotiations over US tariffs, stressing that it "firmly opposes" any agreement that harms its interests.

Washington imposed tariffs of 145% on most Chinese goods, and even 245% on some products, such as electric cars.

In response, China imposed 125% tariffs on US products and said it would continue the trade war "until the end."

However, other US trading partners affected by the 10% additional tariffs benefited from a 90-day suspension of much higher tariffs. Several countries are currently negotiating with the United States to reduce these tariffs.

Beijing responded on Monday by warning these countries against any agreement with the United States that would harm their interests.

"De-escalation will not bring peace, and concessions will not be respected," a Chinese Commerce Ministry spokesperson said in a statement.

The spokesman was responding to a question about the possibility of Washington asking some countries to limit their trade with China in exchange for exemption from US tariffs, according to the statement.

He added that his country "strongly opposes any party reaching an agreement at the expense of China's interests."

He stressed that "if a similar situation occurs, China will never accept it and will take firm countermeasures in response."

China's Ministry of Commerce warned in its statement that "pursuing temporary selfish interests at the expense of others' interests... will ultimately fail and harm others."

These statements come on the heels of several indications of significant progress in negotiations between Washington and its trading partners in the region.

South Korea announced that its finance and trade ministers will travel to Washington this week for high-level trade talks.

The country is particularly concerned that Samsung Electronics and Hyundai Auto would suffer a severe blow if the White House carries out its threats.

Last week, Japan's tariff envoy, Ryusei Akazawa, traveled to Washington, where he held talks with US President Donald Trump.

Japanese Prime Minister Shigeru Ishiba asserted on Saturday that the talks between Japan and the United States could serve as a "model for the world."

"The fact that President Trump personally intervened to negotiate with the Japanese envoy shows that he places importance on dialogue with Japan," he told Parliament on Monday.

He pointed out that "Japan is an ally of the United States and the largest investor and job creator in the country."

Japanese media reported that Tokyo may offer concessions by increasing its imports of American soybeans and rice, or even relaxing auto safety standards.

But the Japanese Prime Minister stressed on Monday that he refuses to accept anything that would harm "safety."

US Vice President J.D. Vance arrived in India on Monday for a four-day visit focused on trade, as New Delhi attempts to negotiate US tariffs on its products.

These talks contrast with the test of strength between China and the United States, which has roiled financial markets and raised fears of a global recession.

Chinese Foreign Minister Wang Yi on Monday reiterated his condemnation of "unilateralism and trade protectionism," calling for "openness" and "mutual benefit," in a statement made in the presence of his Indonesian counterpart, who is visiting Beijing.

He added, "The misuse of customs duties causes tremendous harm to normal economic and trade exchanges between countries."

The US President announced on Thursday that his country is holding talks with China regarding tariffs.

"Yes, we are talking to China," Trump told reporters in the Oval Office, noting that Beijing had contacted Washington "many times."

"I think we will make a very good deal with China," he added.

The Chinese government did not immediately confirm the talks, but has repeatedly called for "dialogue" based on "equality."
