Regional papers, which usually focus on local news, are devoting their front pages to a staunch defence of China's claim over the disputed waters.
The papers dismiss the tribunal's decision outright, and many feature maps that depict disputed islands in the South China Sea as belonging to China.
This concerted propaganda effort will have considerable clout. China Statistics Press, an official agency, says China has around 1,900 newspaper titles.
Dahe Daily in central Henan province shows the words "Hague arbitration" on a piece of scrap paper being thrown into a bin.
Nanjing paper Modern Express shows a map of China and the disputed South China Sea region. It says: "We neither accept, nor recognise this."
Guangzhou paper Information Times has a similarly striking cover, with the same words in bold against a plain white background.
New Express Daily, in southern Guangdong, depicts the word "arbitration" on a piece of paper being ripped up.
Shenyang Evening Post, northeast Liaoning province, carries the headline: "Shared hearts and shared defences, this is our sea."
Another paper from the region, Liaoshen Evening Post, simply says "NO" on its front cover.
From the east, Hangzhou-based Youth Times shows a map of China with the South China Sea included. Its headline reads "China: Nothing more, nothing less".
The Beijing Morning Post carries a picture of China superimposed against a sea, and the headline: "South China Sea Islands: China's territory".

Anastasia Deyeva, 24, has been appointed a deputy interior minister, unprecedented for anyone of her age. And some Ukrainians think she is not qualified for the job.
"There's nothing wrong about a woman being an adviser, especially if she's pretty and smart," was one typical comment on Facebook. "But it's very wrong if she's that young and has no experience. Or the wrong kind of experience."
As debate swirled around Ms Deyeva's appointment, another young woman was selected for the highly charged job of running a campaign to purge the government of corrupt officials. Anna Kalynchuk, 23, studied law and was already part of the government's anti-corruption department.
Ms Deyeva had to deal with closer scrutiny than most public officials when nude photos of her were posted online.
More tasteful pictures have since appeared on Ukrainian lifestyle website Style Insider.
Nothing to do with her work, insisted Ms Deyeva.
She defended her credentials, telling one interviewer (in Russian) she had exactly the right experience for the job. She was an aide to an MP, worked for a Swedish energy company and was considered suitably qualified enough to be offered an interior ministry job in 2015.
But her promotion to become Ukraine's youngest ever deputy minster unleashed a torrent of criticism.
"I knew that I'd end up in the limelight, that there would be criticism and biased commentary. But I never expected such vile attacks," she says.
Ms Deyeva's boss, Interior Minister Arsen Avakov, is firmly behind her.
"The main thing people have against her is that she's young," he wrote on his Facebook page (in Russian), adding that the criticism was based on outdated attitudes. "In the Soviet tradition, this sort of job was for a monster, but we've hired a girl. Maybe so, only we do things differently in my ministry," he said.
He is not alone in thinking it is time for Ukraine to move on.
"I am extremely glad that you're one generation younger than me," wrote Denis Kazvan, formerly an interior ministry adviser. "People like you do not need to spend 40 years wandering through the desert to get rid of the Soviet gene of slavery. People like you are free inside."

Newspapers in China have gone into propaganda overdrive, a day after a tribunal in The Hague ruled against Beijing's claim to the resources of much of the South China Sea.

Political storms are nothing new to Ukraine, but unusually the latest surrounds a young woman who has landed one of the country's top police and security jobs.
