Shellfire From Myanmar Enters China, Drawing a Rebuke

BANGKOK — China said Thursday that it had expressed “grave concern” to the Myanmar government after a shell, apparently fired during fighting between Myanmar troops and ethnic rebels, landed in Chinese territory, and a Chinese government spokesman called for an immediate cease-fire.

The Chinese response was unusually strong given the close ties between the two countries in recent years, and it suggested that China was growing increasingly impatient and nervous about the Myanmar government’s campaign against ethnic Kachin rebels.

I know bit Drastic but if China went in to Myanmar, can you see UNSC condemning it, considering NATO's deployment towards Syria
