As the preparatory lower-level trade talks between the Chinese and US officials were underway on Monday, Washington sailed two guided-missiles within 12 nautical miles of the Spratly Islands as part of the US Navy's "freedom of navigation operation".
"We firmly oppose this. China urges the US side to stop such provocations and respect our efforts to uphold the stability and peace in the region," Chinese Foreign Ministry spokesperson Hua Chunying said here.
"With the concerted efforts of China and Asean (Association of Southeast Asian Nations) countries, the situation in the South China Sea is peaceful and stable, but now the US is making provocation and creating tensions and trying to harm and peace and stability there.
"China has indisputable sovereignty over Nansha islands, Mischief reefs and neighbouring waters. We always respect the freedom of navigation by other countries under the international law but we firmly oppose any country's action to harm sovereignty and security under this pretext," Hua added.
The issue has also emerged as a friction point between China and the US after an UN-backed tribunal rejected Beijing's territorial claims in the waters in 2016. China rejected the ruling, while Washington wanted Beijing to follow it.
The US keeps sending warships in the resource-rich waters through which $5.3 trillion worth of goods passes through annually.
Asked if Washington's move could cast a shadow on trade talks in Beijing this week, Hua said: "I believe you see through the small tricks by the US side. We believe solving trade issues through dialogue and discussion will meet the aspiration of the whole world and this also in the interest of China and the US."
US Treasury Secretary Stephen Mnuchin and trade representative Robert Lighthizer will meet Chinese Vice Premier Liu He on Thursday to clinch a deal before the March 1 deadline of the truce in the ongoing trade row.
If there is no agreement, then the US will hike tariffs on Chinese goods worth $200 billion from the existing 10 per cent to 25 per cent.
