A top Chinese military officer recently inspected the Nansha Islands in the South China Sea Kyle Murphy Jersey , the defense ministry said Friday, after the top US defense official visited an aircraft carrier transiting the disputed waters.
The coincidence of the two top military leaders' presence in the South China Sea showcased continuing tensions in the water, observers said.
Fan Changlong, vice chairman of the Central Military Commission, was briefed on the construction projects on Nansha's islands and reefs.
China's Ministry of National Defense said on its official website that the construction projects are going smoothly. Those projects, including lighthouses, automatic weather stations, oceanic observation centers and oceanic research facilities, will provide public services for the international community, according to the Xinhua News Agency. But these projects have been criticized by other claimants to the waters.
Five lighthouses have been completed, and four of them are now operational, the ministry added.
Fan also met with officers and soldiers stationed on the islands as well as construction workers.
"The rare official announcement of Fan's presence in the South China Sea has sent out a strong signal to the US, which intervenes in the disputes with some of China's neighboring countries, indicating the Chinese military's increasing determination to defend its maritime rights and interests as well as its readiness for possible escalating confrontations," Liu Feng, an expert in Chinese maritime issues, told the Global Times on Friday.
In particular, China will continue constructing necessary facilities for self-defense, if the US insists on increasing its military presence in the waters, Zhu Feng, director of the Collaborative Innovation Center of South China Sea Studies at Nanjing University, told the Global Times on Friday.
On the same day, US Defense Secretary Ash Carter flew to the nuclear-powered USS John C. Stennis for a two-hour visit, Reuters reported on Friday.
"What's new is not an American carrier in this region," Carter said aboard the Stennis, where he met US troops and observed flight operations. "What's new is the context of tension, which exists, which we want to reduce."
During Friday's visit, Carter was accompanied by Philippine Defense Secretary Voltaire Gazmin.
"Following US-Philippines military exercises, Carter sailing in the water with an US aircraft carrier further demonstrated the US stance to step in the South China Sea disputes," Liu said.
Echoing Liu, Zhu said that the US is increasingly pressuring China with the threat of armed confrontation.
"If certain people from the US sincerely wish to peacefully resolve the issues, we hope that their actions would match their words and be genuinely conducive to resolving disputes," China's foreign ministry spokesman Lu Kang told a daily briefing on Friday.
"Some US officials often replace freedom of navigation in the argument," Lu noted, saying the US side has failed to offer one single example where the safety and freedom of civil navigation in this region has been affected since the South China Sea disputes emerged over 40 years ago.

SAN FRANCISCO, Sept. 16 (Xinhua) -- New research suggests fox squirrels organize their stashes of nuts by variety, quality and possibly even preference, by using "chunking," a cognitive strategy in which humans and other animals organize spatial, linguistic, numeric or other information into smaller more manageable collections.
Detailed in a paper published this week in the Royal Society Open Science journal, researchers at the University of California, Berkeley, noted that fox squirrels stockpile at least 3,000 to 10,000 nuts a year and, under certain conditions, separate each cache into quasi "subfolders" similar to those in a computer storage system, one for each type of nut.
The study used combinations of locations and nut sequences on various groups of fox squirrels.
In one experiment, each of the squirrels were fed 16 nuts, one after another, under two separate conditions: Some were fed at the locale where they had cached the previous nut fed to them while others were fed at one central location, to which they would need to return if they wanted another nut.
Some squirrels were given 16 nuts in rows of four, say, almonds followed by pecans, followed by hazelnuts and then walnuts, while others received 16 nuts in random order.
Using hand-held Global Positioning System, or GPS, navigators, the researchers tracked the squirrels from their starting location to their caching location, then mapped the distribution of nut types and caching locations to detect patterns.
The research team found that the squirrels who foraged at a single location frequently organized their caches by nut species, returning to, say, the almond area, if that was the type of nut they were gathering, and keeping each category of nut that they buried separate.
Meanwhile, the squirrels foraging in multiple locations deliberately avoided caching in areas where they had already buried nuts, rather than organizing nuts by type.
The findings over a two-year period from 45 male and female fox squirrels in wooded locations on the UC Berkeley campus suggest that when lacking the cognitive anchor of a central food source, the reddish gray, bushy-tailed rodents utilize a different and perhaps simpler problem-solving approach to avoid the areas where they had previously cached.
Presumably, according to the authors, sophisticated caching techniques maximize the squirrels' ability to remember where they've stored their most prized treats while at the same time hiding them from potential pilferers.
"This is the first demonstration of chunking in a scatter-hoarding animal, and also suggests that squirrels use flexible strateg.
