(Bloomberg) -- China’s President Xi Jinping called on citizens to join a "new Long March," a phrase he’s used before to characterize achieving progress despite hardship, as the U.S. weighs stronger restrictions on Chinese technology companies amid a deepening trade war.

Xi made the remarks on Monday while leaving the Long March memorial garden in Jiangxi Province, according to a video clip released by state television. The site marks the starting point of a lengthy migration from 1934 by the Communist Party’s military after setbacks that forced it to join with troops in northwest China.

"We came to the starting point of the Long March to experience the Red Army’s departure at that time," Xi said to a cheering crowd as he departed. "It’s a new Long March now, and we must start all over again."

While the comments have historical significance, Xi last March also called the push to turn party proposals into reality a "new Long March" and state-run Xinhua News Agency defined the phrase as the realization of the Chinese dream in a story on Wednesday. Yet, the timing of the clip -- released one day after Xi actually made the remarks -- and the decision to air only one line, could be read as rallying the nation for what is set to be prolonged conflict with the U.S.

Xi’s trip to Jiangxi came after talks between Beijing and Washington stalled, with U.S. President Donald Trump accusing China of backing out of a deal that was taking shape and saying that China reneged on an agreement to legislate various agreed reforms.

On Monday, Xi visited a rare earths facility in Jiangxi, fueling speculation that the strategic materials could be weaponized in China’s tit-for-tat with the U.S. on trade. The VanEck Vectors Rare Earth/Strategic Metals ETF, which tracks producers, jumped the most since 2011 on Monday.

Trump is considering blacklisting up to five Chinese surveillance companies including Hangzhou Hikvision Digital Technology Co. and Zheijiang Dahua Technology Co., according to people familiar with the matter. The restrictions would be similar to those imposed last week on Huawei Technologies Co., and would sharply curtail the companies’ access to U.S. market and American suppliers.

The U.S. policy of "maximum pressure" on Huawei has proved again that China can’t buy its way into modernization, according to a commentary published on Wednesday in the People’s Daily, the flagship newspaper of the Communist Party. The paper cautioned that "China’s economic security can not be ensured unless it achieves technology independence."

The paper also rebutted U.S. accusations of "China backtracking" in the trade talks in another commentary on Wednesday, saying the claims were deliberately made up by U.S.
