"The main problem is that certain external forces are unhappy that the situation in the region has improved. They are making provocations, trying to sow chaos and send a heavily-armed craft to the South China Sea in a show of force," he said.
Wang Yi, who was speaking at an annual press conference, referred to militarization as the biggest challenge for stability in the region.
Yi continued by saying that China had always pursued the principle of non-interference in the affairs of foreign states and opposed the use of force in solving international problems.
"[China is committed to] political settlement of existing problems, dialogue, as well as to holding of negotiations in order to address any tensions and conflicts, Beijing firmly opposes the use of force," the minister said.
Wang indicated that China had its own specifics when it comes to addressing pressing international issues, adding that the country's policy was based on three main aspects: peaceful character, legitimacy and constructiveness.
Among other pillars of the Chinese foreign policy doctrine, the minister mentioned non-interference in internal affairs of other states and protection of their sovereignty.
The US has been further escalating the situation by conducting patrolling and performing drills with its allies in the region. Washington claims that its actions are to ensure freedom of navigation, while Beijing calls the move a violation of its territorial sovereignty.
