BEIJING - The brewing China-U.S. trade conflict features two leaders who've expressed friendship but are equally determined to pursue their nation's interests and their own political agendas.
But while President Donald Trump faces continuing churn in his administration and a tough challenge in midterm congressional elections, China's Xi Jinping leads an outwardly stable authoritarian regime. Xi recently succeeded in pushing through a constitutional reform allowing him to rule for as long as he wishes while facing no serious electoral challenge.
Here's a look at some of the issues that could determine the outcome of the trade spat:
Although Mr. Trump sounded tough on the campaign trail and has challenged Beijing over trade and Taiwan, he professes admiration for his Chinese counterpart and complimented him on his ability to remove term limits on his presidential rule.
"President Xi and I will always be friends, no matter what happens with our dispute on trade," Mr. Trump said in a tweet Sunday. "China's great and Xi is a great gentleman," he said in remarks at a Republican fundraiser last month obtained by CNN.
Xi has generally limited his comments to emphasizing the benefits of a close China-U.S. relationship and thanking Mr. Trump in a phone call on March 10 for congratulating him on his obtaining a second term as president. China also hailed as successes a pair of summits between the leaders in the U.S. and China over the past year.
Both Mr. Trump and Xi come from privileged backgrounds, although their routes to political power were decidedly different. However, both have built their reputations on a robust form of nationalism, with Mr. Trump promoting "America First" and Xi identifying himself with the "Chinese Dream" of rising prosperity accompanied by muscular defense and foreign policies.
President Trump was born the son of a New York City real estate mogul and rose to his current post on a populist wave after a career as a property developer and reality TV star. Xi's father was a colleague of Mao Zedong, whose influence is believed to have aided his rise through a series of military, government and Communist Party positions before he was named party leader in 2012.
Both also show an affection for strong-man leadership, and while American democracy is far removed from China's one-party authoritarian system, Mr. Trump's verbal attacks on the mainstream media and certain judges have drawn criticism. They both also place a strong emphasis on the military, including increased defense budgets and an appreciation for military parades, two of which Xi has led during his time in office.
Xi's plan to create Chinese global competitors in fields including robotics, electric cars and pharmaceuticals is seen as precipitating the current crisis, while Mr. Trump appears motivated by a desire to shore up America's manufacturing strength.
Neither wants to be seen as backing down, and though Xi's usually soft-spoken manner contrasts Mr. Trump's trademark bravado, both "are thin-skinned bullies who place a lot of value on portraying strength," said Liz Economy, a leading academic on China and author of "The Third Revolution: Xi Jinping and the New Chinese State."
"This makes it difficult to ramp down in this one-on-one tariff death match," although both have the capacity via Twitter or state media to trumpet their success and ignore any failings once the dispute has concluded, Economy said.
Let's make a deal
While the current dispute has focused on trade, many other factors are in play, bringing out the bargaining qualities and transactional natures of the two leaders and their administrations. Opinions on who has the upper hand differ widely.
By pursuing the tariff threat and backing complaints about intellectual property theft, President Trump has "successfully changed the fundamentals of ... U.S.-China relations," said Miles Yu Maochun, a China politics expert at the U.S. Naval Academy in Annapolis, Maryland.
Yu also points to recent U.S. policy on North Korea, particularly Mr. Trump's acceptance of an invitation to talks with North Korean leader Kim Jong Un as early as next month that appeared to catch Beijing off guard.
Shortly afterward, Kim paid an unexpected debut visit to China as leader in what some saw as an attempt by Beijing to reassert its centrality in resolving tensions over the North's nuclear weapons and missile programs.
Yet, as North Korea's most important trade partner and political ally, China wields considerable influence, and its willingness to enforce U.N. sanctions has built up its credibility as a reliable international partner.
China also stands to bring additional pressure on Taiwan, the self-governing island democracy it claims, and which is closely linked to Washington despite technically unofficial ties.
While Beijing responded mildly to Mr. Trump's early outreach to the island's independence-leaning government, recent moves such as the appointment of hawkish new National Security Adviser John Bolton, the passage of a U.S. law encouraging more intergovernmental exchanges and an agreement to pass submarine manufacturing technology to Taiwan are hardening views among anti-American nationalists in China.
Beijing's Taiwan Affairs Office on Wednesday warned against additional moves to strengthen relations with Taiwan, amid reports that Bolton could visit the island this year.
"Any attempt to play the 'Taiwan card' would only be futile," spokesman Ma Xiaoguang said at a biweekly news conference. China, Ma said, would "not hesitate to protect our core interests."
Challenges at home
While Yu cited domestic support for Mr. Trump's trade approach to China, Xi can likely command even stronger backing at home for a muscular approach toward what Beijing portrays as a conflict resulting from U.S. unilateralism and hegemony.
Xi also faces no electoral challenge such as the one the president's Republican party will confront in midterm congressional elections later this year, when Mr. Trump's handling of the U.S. economy and a host of other issues will be in the mix. Mindful of American voters, especially in the agricultural and industrial sectors, Xi appears set to use such leverage for maximum gain.
"Xi will follow a tough but well directed path designed to hurt specific interests that will complain loudly," said Joseph Fewsmith, a Boston University expert on Chinese foreign policy.
While Xi is broadly considered the most powerful leader since Mao, China "only appears to be united and confident in its approach," said Economy, the academic, adding that the outside world has limited insight into policy debates within China.
