China-US relations are now in an unprecedented predicament since the two countries established diplomatic ties.Though China has no intention to push nor escalate the strategic competition with the US and attempts to look for space for compromise that may accommodate the strategic interests of both countries,the China-US relations are neither defined nor steered by the unilateral efforts made by China.As the US has been bringing China under mounting strategic pressure,it will become inevitable that China-US strategic competition will only intensify for the moment and continue in the future.Strategic competition among major countries,if intensified,will transmit the pressure to their neighboring regions.In this case,the US will be an unprecedentedly critical factor in China’s relations with its neighboring countries and generally,a significantly negative factor against the backdrop of strategic competition.It remains an immediate and future challenge for China to handle its diplomatic relations with neighboring countries when the US interruption is mainly present.
