China media: Obama's Asia tour
Papers discuss US President Barack Obama's upcoming four-nation Asia tour amid growing regional tensions.
Mr Obama will arrive in Japan on Wednesday for a three-day visit, before heading to South Korea, Malaysia and the Philippines.
Tensions between China and its neighbours, particularly Japan and the Philippines, are high over maritime territorial rows.
China has often expressed its displeasure towards what it sees as Washington's "support" for other regional nations.
The People's Daily feels Mr Obama's visit to these countries will further escalate problems in the region.
"It is not difficult to see the ulterior motives of Mr Obama's trip. Most of the countries that he is visiting are embroiled in territorial disputes with China. Is Mr Obama going to be a fire-fighter or someone who is fanning the flame?" it asks.
It alleges that the US "is secretly supporting the provocative behaviour of Japan and the Philippines".
Jin Canrong, an expert on international affairs from Renmin University, tells Xinhua News Agency that the US wants to assert its presence in the region.
"In fact, the Americans have the confidence to control Japan, and hope that it could play a bigger military role in Asia," he adds.
The Economic Information points out that trade and economic issues will also be on the agenda because the US is eager to expand its market in Asia.
"Mr Obama's trip is also an attempt to strengthen the US presence in Asia and reinforce its economic strategy in this region," it says.
Meanwhile, media are excited over a six-minute long music video featuring China's first aircraft carrier, the Liaoning.
The music video has been made to help "realise the great Chinese dream", reports say.
The video, uploaded by state-owned Aviation Industry Corporation of China, shows the flight training process on the carrier with the song "Lead the Dreams" sung by an ethnic minority singer.
The video has been released ahead of the 65th anniversary of the founding of the Chinese Navy, according to Xinhua. The anniversary will be celebrated on 23 April.
"It rocks, just like a blockbuster movie," the Guangzhou Daily exclaims.
The Global Times reports that the video has sparked "intense discussion online", with many netizens expressing their confidence in the nation's defence forces.
"The Chinese military is not used to disclosing or displaying its aircraft or training in such a high-profile way due to concerns like national security leaks, but this video has used many artistic methods to show operations on the carrier without revealing any secrets," Li Jie, a military expert, tells the daily.
And finally, papers debate the use of Google Glass - a wearable computer mounted on a headset - after a law enforcer used the device during his street inspection.
According to local media reports, Jiang Yifan, an urban administrative inspector, or chengguan, used Google Glass to record his inspection rounds in Jiangsu Province.
Chengguan have been seen as bullies and are often accused of brutality against street vendors.
On Saturday, an angry crowd attacked five inspectors in Zhejiang province during a confrontation.
The Hunan Xiaoxiang Morning Herald points out that it is more important for the officers, who have been "demonised", to abide by the law than to use new technology to film confrontations.
"During Saturday's incident, the inspectors beat up a passerby and it sparked anger among the crowd… The inspectors do not need Google Glass, instead they should exercise self-restraint," it says.
