China-U.S. trade tension needs control

China and the United States have met a bumpy start to 2018 as scepticism about Chinese investment and trade are clouding over Washington.

The U.S. government rejected a merger by China's Ant Financial with U.S. money transfer company MoneyGram International Inc. over national security concerns on Tuesday.

It is not surprising that a number of Chinese companies have hit the buffers in Washington as trade tensions between the two countries are flaring.

The bonhomie that grew between China and the United States in Beijing in November, when the two signed hundreds of billions of dollars of deals, seems to be fading away as the U.S. side is stuck in a zero-sum mentality.

In the last 30 days of 2017, the U.S. government launched a Section 301 investigation into Chinese intellectual property and technology transfer, self-initiated probes into Chinese-made aluminum products, and rejected China's market economy status at the World Trade Organization.

The hawkish turn became ear-piercing when President Trump described China as a strategic "competitor" in his first national security strategy in December, accusing the China of pursuing economic aggression designed to weaken America.

Are there reasons for optimism in 2018? An injection of hope is urgently needed for the world's top two economies to sail the charted course.

The first batch of prototype subway cars to be eventually manufactured in Massachusetts arrived in Boston days before Christmas.

The new prototype was built by a China-based plant of CRRC, the country's largest rail car maker. Mass production will begin at the company's factory in Springfield, Massachusetts to serve the Orange Line of the Boston metro, the world's oldest transit system.

This story highlights a shift in the economic relationship between the world's top two economies: "Made in China" is increasingly being replaced by "Made by China in America."

According to a report by the National Committee on U.S.-China Relations and Rhodium Group, employment by Chinese-owned firms across America jumped nine-fold from 2009 to 140,000 in 2016.

Stephen Orlins, President of the National Committee on U.S.-China Relations, said that for years U.S. companies invested in China, made profits and built communities, becoming strong supporters of constructive U.S.-China relations.

In the face of a rising China, the United States, however, feels uneasy.

China has not hesitated to make it clear that it is not seeking global dominance, rejecting a zero-sum mentality between countries, especially between the United States and China. Cooperation is the only correct choice for both.

China's case is not well received by the United States. With deep-rooted strategic mistrust toward China, U.S. politicians have failed to catch up with China's understanding of cooperation and adopted an increasingly protective and isolationist approach.

When China proposes building the world into a community of shared future, it does not distinguish between competitors and partners. At this moment, the real test facing policymakers is whether or not they can maximize cooperation and manage competition so that it does not escalate into conflict.

Cooperation is essential for China and the United States to handle growing common challenges and interests. Narrow-mindedness and rigidity will lead to a zero-sum game. But both will be better off if they come together, since their common interests are greater than their differences.

China and the United States are about to ride a bumpy journey in trade in 2018 if the U.S. government goes it own way, and retaliatory measures by China could be on the table.

But the price is too high for the two peoples to pay if scepticism grows and tension escalates. Composure and pragmatism are needed to steer trade ties safe and sound.
