Updated | Russian President Vladimir Putin and Chinese President Xi Jinping have easily won national elections that will propel their respective drives to expand global influence and improve military capabilities, as experts say people are seemingly turning away from the Western-style world order traditionally led by the U.S.

Putin reportedly secured 76.6 percent of votes Sunday to win an unprecedented fourth term as president, which—along with his four-year tenure as prime minister—would give the Russian leader nearly a quarter century of power, a feat rivaled only by Soviet leader Joseph Stalin.

Meanwhile, Chinese President Xi Jinping faced even less opposition during his unanimous re-election vote Saturday at the 13th National People's Congress. The ruling Communist Party's recent abolition of presidential term limits means Jinping could potentially enjoy an even longer term than Putin, another Cold War–era feat not seen in China since the days of Mao Zedongwho led the country's Communist revolution.

The two men preside over countries that represent the most potent challenges to the U.S. in terms of global military power and political influence. As Moscow and Beijing both look to check Washington's ambitions abroad, they have boosted their own countries' cooperation with one another and, after back-to-back victories last weekend, Putin and Xi were among the first to congratulate one another.
