When I think about coastlines, I imagine where land ends and possibility begins. A shoreline is not just a place where waves crash; it is a border of security, trade, and power. For China, however, that border has always felt too narrow. Its 19,884 miles of coastline may sound immense, but it is only one-fifth the size of the United States’ 95,471 miles. To compensate, Beijing has not just built ports—it has built islands. Land has been dredged from the sea, the coast extended artificially, as though geography itself could be rewritten.
China’s hunger for reach goes far beyond sand and cement. Its ambitions stretch deep into the South China Sea and across the Indo-Pacific. These waters carry more than 30 percent of global shipping, and beneath them lie oil, gas, and fisheries. Whoever commands them controls not only trade routes but also the levers of future prosperity. Beijing knows this. Its strategy is not simply about geography—it is about power, security, and symbolism.
I write this not as an outside observer, but as someone who was born and raised in China. I understand how the Chinese Communist Party operates—the aggressiveness, the uncompromising insistence on control, the ability to fuse propaganda with policy until it feels inevitable. Having seen this firsthand, I cannot separate the facts of Beijing’s maritime expansion from the deeper reality of how the regime approaches every challenge: with dominance as the ultimate goal.
The Muscle of Military Signaling
China today commands the world’s largest navy by ship count: more than 370 vessels, projected to exceed 435 by 2030. This rapid expansion is not just about defending the homeland; it is about projecting strength far beyond the shoreline.
The tactics are increasingly coercive. In September 2024, a Chinese ship rammed a Philippine coast guard vessel near Second Thomas Shoal, injuring eight sailors while U.S. media filmed the encounter. By early 2025, Beijing was openly threatening to blockade the shoal and remove the grounded Philippine ship stationed there as a symbol of sovereignty. These are not isolated incidents; they have become the “new normal.”
Taiwan faces similar pressure. The number of Chinese aircraft crossing the Taiwan Strait median line soared from under 1,000 in 2021 to more than 3,000 in 2024. January 2025 alone saw 248 incursions, a record high. Add to that water-cannon attacks, cyber intrusions, and daily patrols by coast guard and fishing militias, and it is clear Beijing is rehearsing for something larger—a blockade, perhaps even an invasion.
Japan, too, is pressed in the East China Sea. Chinese vessels circle the Senkaku Islands year after year, testing Tokyo’s patience and resilience. Meanwhile, reports of Chinese military expansion in Cambodia suggest Beijing is planting flags well beyond its immediate neighborhood.
All of this paints a picture of a China intent on rewriting the rules of regional security, one ship, one flyover, one artificial island at a time.
The Pen of Cultural Infiltration
Yet brute force is only half the story. Beijing also wields softer tools: narratives, culture, and persuasion. Since 2007, when the Communist Party elevated “soft power” to a strategic priority, China has invested heavily in shaping how others see it. The goal is clear: to tell “good stories” about China that drown out criticism and normalize Beijing’s rise.
Take South Korea. In 2004, Seoul became home to the very first Confucius Institute—part of a sprawling global network designed to teach Chinese language and culture but criticized for spreading propaganda. By 2021, South Korea had more of these institutes than any other country. Beijing’s influence campaigns have since expanded into elections, with AI-generated disinformation and troll farms aiming to sway public opinion.
Japan has felt this pressure through cyberattacks and espionage. The hacking group MirrorFace has targeted government agencies and corporations since at least 2019, stealing sensitive data and planting disinformation. A restaurant in Tokyo’s Roppongi district—run by a former Chinese diplomat—was even exposed as a hub for gathering intelligence from Japanese elites. Influence here is not abstract; it is intimate, dining at the same tables where leaders make decisions.
Taiwan, meanwhile, lives under a constant fog of manipulation. From pro-China livestreams by immigrant wives to TikTok campaigns targeting youth, Beijing works relentlessly to divide society from within. Economic carrots—market access, trade deals—are dangled before businesses and politicians, while sticks come in the form of bans on agricultural exports or tourism. It is not just about pressuring the government; it is about reshaping the everyday conversations of ordinary Taiwanese people.
And then there is the Philippines, where espionage cases and troll farms are multiplying. Chinese agents have been arrested near naval bases with drones and surveillance gear. Cyberattacks have infiltrated government networks and hospitals alike. Disinformation floods social media, amplifying anti-U.S. voices while Beijing’s coast guard intimidates fishermen at sea.
The Pattern Beneath the Waves
At first glance, these stories may seem scattered—one about ships, another about schools, another about social media influencers. But put them together, and the pattern emerges: China is running a coordinated campaign that blends hard power, sharp power, and soft power. It bullies on the seas while whispering in the classrooms. It hacks into servers while sponsoring cultural exchanges. It funds disinformation campaigns while promising economic opportunity.
The aim is not conquest in the old sense of the word. It is influence—subtle, persistent, normalized until resistance feels futile. By tailoring its approach to each country—cultural diplomacy in South Korea, cyber intrusion in Japan, grassroots infiltration in Taiwan, maritime coercion in the Philippines—Beijing maximizes its reach while maintaining plausible deniability.
Why This Matters
For the Indo-Pacific, the stakes are existential. If China succeeds, the region’s democratic institutions may erode from within while its territorial lines are erased from without. For the world, the stakes are no less significant. The South China Sea is not just China’s backyard; it is a global artery of trade. The narratives Beijing spreads are not just for its neighbors; they ripple through social media feeds worldwide.
And for me, as a Chinese national, this is deeply personal. I grew up under a system that rewards conformity and punishes dissent, that cloaks aggression in the language of stability and peace. When I see Beijing expand outward with both military might and cultural manipulation, I recognize the same pattern I witnessed inside: a relentless drive to dominate, to control, to shape the future so completely that no alternative seems possible.
Power is not only about armies and weapons. It is also about stories—who tells them, who believes them, and how they shape the world we live in. Beijing understands this. Its expansion is not only territorial but also cultural and cognitive. It seeks to occupy minds as much as it seeks to occupy islands.
When I reflect on all this, I think again of coastlines. They are not just edges of land; they are thresholds of imagination and will. China’s reach may grow, but so too must the vigilance of those who care about freedom, transparency, and truth. If Beijing is determined to redraw the map, then the rest of us must be just as determined to defend the open seas of both water and ideas.
