Taiwan's coast guard pushed back another incursion by Chinese ships near Kinmen, a sign that pressure around Taiwan's front-line islands keeps rising.

• Four Chinese coast guard ships entered restricted waters near Kinmen on Sunday, sailing in two paired formations.
• Taiwan's coast guard sent four patrol boats to match them one-on-one and used Chinese and English radio warnings to force them out.
• All four Chinese ships left the restricted zone within about two hours.
• This is the second such incursion in a few days, after a similar one on October 30, suggesting the pressure is becoming more frequent.
• Taiwan says China is using these patrols as a cover to slowly expand its claims over the waters, not real law enforcement.

Outlook: Taiwan says it will keep closely tracking Chinese ships near Kinmen and keep pushing back without escalating, so more of these standoffs are likely in the coming weeks.
