TOKYO (AP) — China and Japan took another step toward mending their troubled relations Monday, resuming high-level economic talks for the first time in nearly eight years.

Foreign Minister Wang Yi led the Chinese delegation, becoming the first foreign minister to visit Japan for bilateral talks since 2009.

Asia’s two largest economies have been trying to improve strained ties and now have further reason to cooperate in the face of President Donald Trump’s moves to impose tariffs on imports from their countries and his demands that they open their markets more to American exports.

Wang, meeting with Japanese Prime Minister Shinzo Abe, noted the threats of rising unilateralism and trade protectionism.

Abe heads to the United States on Tuesday to meet with Trump to discuss both trade and Trump’s plans for a summit with North Korean leader Kim Jong Un.

Japan’s leader said that he is seeking China’s cooperation in efforts to get North Korea to abandon its nuclear weapons development in a full and irreversible way.

Earlier Monday, Japan and China held what was billed as the fourth Japan-China High-Level Economic Dialogue, the first such meeting since August 2010.

Wang met with his Japanese counterpart, Taro Kono, for nearly four hours on Sunday, Japan’s Foreign Ministry said. The two ministers agreed on the importance of arranging respective visits by Abe to China and Chinese President Xi Jinping to Japan.

— Facing a possible U.S. tariff hike, one of China’s biggest ball bearing makers, Cixin Group, is weighing plans to rush shipments to American customers before the increase makes its sales unprofitable.

The company in the eastern city of Ningbo is among exporters of goods from motorcycle parts to electronics that are scrambling to cope with President Donald Trump’s higher duties by shipping early, raising prices or finding new markets.

The 25 percent increase would turn Cixin’s profits to losses in the U.S. market, which takes 30 percent of its exports, according to Wang Liqiang, a company manager.

“We are considering manufacturing as many ball bearings as possible for the U.S. market before the imposition of tariffs,” said Wang. “We can do it by working overtime.”

Some companies are looking at ways to hide their Chinese origin by shipping goods through other countries.

“Maybe customers will buy from South America, and then South America sells to the U.S.,” said Yvonne Yuan, a sales manager for Shenzhen Tianya Lighting Co., a manufacturer of LED bulbs.

Trump says higher duties on $50 billion of Chinese goods are meant to punish Beijing for stealing or pressuring foreign companies to hand over foreign technology.

The plan targets goods U.S. officials say benefit from improper Chinese policies including machinery, industrial components and aerospace, telecoms and other technology.

Trump left time to negotiate. A public comment period runs through May 11, with a hearing scheduled May 15.

Economists and Chinese officials say the tariff hike’s overall impact on China should be limited. But for exporters that depend on the U.S. market, the potential costs are alarming.

Knock-on effects could greatly increase the impact, Moody’s Investors Service researchers said in a report. It said that Chinese manufacturers that supply inputs to targeted sectors would see reduced demand and more pricing pressure, spreading the effects of tariffs deeper into the Chinese economy. Manufacturing and processing of metals and metal products, as the key input sectors for technology-product manufacturing, would be hurt the most.

Chinese exporters supply most of the world’s mobile phones, personal computers, televisions, toys and other light manufactured goods from thousands of factories.

They are flexible and resourceful but many are struggling with higher costs and slowing demand. China’s total exports last year rose 7.9 percent, down from the heady double-digit rates of the past decade.

The United States buys about 20 percent of China’s exports. But Americans are especially important to exporters because they buy electronics and other high-value goods, including many targeted by Trump’s tariffs.

Some exporters already are reeling from previous U.S. tariff increases of up to 500 percent on washing machines, solar modules and some metal products, meant to offset what the Trump administration says are improper subsidies that allow them to sell at unfairly low prices.

Others are confident American customers cannot do without them.

Makers of motorcycle components plan to use that leverage to ask buyers to split the cost if tariffs rise, said Pan Jianle, an official of the Motorcycle Parts Association in Wenzhou. She said they export worldwide but the United States is their No. 1 market.

“The U.S. motorcycle parts industry relies heavily on China,” said Pan. “It is difficult for U.S. customers to find products with good quality and value for money from other places.”

Such a politically charged conflict has left companies and local Chinese officials jumpy.

Pan declined to provide the value of exports of motorcycle components to the United States. A few hours later, the Wenzhou city government’s foreign affairs office called AP to ask about its interviews.

Electronics manufacturers also plan to ask buyers to share higher costs, said Li Zengyou, secretary general of the local manufacturing chamber of commerce in the eastern city of Zibo in Shandong province.

Zibo’s electronics exports to the United States last year totaled $1 billion, according to Li. That would mean if the tariff hike applied to all their sales, it could add $250 million to the cost.

If higher tariffs hit, “they will raise the price,” said Li. “If the U.S. customers failed to accept it, they would stop exporting to the United States and turn to explore other markets.”

Ningbo-based Cixin Group’s margins in the United States are about 10 percent, which would be wiped out by a 25 percent tariff hike, said Wang. The company also exports to Europe and Latin America.

“We can’t bear all the costs,” he said. “We can try to increase our exports to other countries, but it is not easy to establish a long-term relationship with new customers.”
