President Obama has called for a "peaceful resolution" to maritime disputes at the ASEAN summit. His statement comes as the Taiwanese Defense Ministry said Beijing deployed surface-to-air missiles in the South China Sea.

US President Barack Obama and leaders of Southeast Asia concluded a "Special Leaders Summit" - the first of its kind in the US - on Tuesday, calling for "tangible steps" to "peacefully resolve" disputes in the South China Sea.
"The United States and ASEAN [Association of Southeast Asian Nations] are reaffirming our strong commitment to a regional order where international rules and norms and the rights of all nations, large and small, are upheld," Obama said at a press conference at the end of the summit.
"We discussed the need for tangible steps in the South China Sea to lower tensions including a halt to further reclamation, new construction and militarization of disputed areas," he added.
While China says it has a historic right over the South China Sea, ASEAN members that include the Philippines, Malaysia, Vietnam and Brunei also claim land features in the strategic thoroughfare for international shipping.
Surface-to-air missile system
Obama's statement came on the heels of a report that China had deployed an advanced surface-to-air missile system on one of the disputed islands in the South China Sea.
Taiwan Defense Ministry spokesman Major General David Lo on Wednesday told the Reuters news agency that missile batteries were placed on an island that has also been claimed by Taipei.
"Interested parties should work together to maintain peace and stability in the South China Sea region and refrain from taking unilateral measures that would increase tensions," Lo said.
Beijing has built several artificial islands in the disputed area, some with airstrips, in a bid to assert its sovereignty.
In 2013, the Philippines brought its claims against Beijing to an international court, resulting in an arbitral tribunal based in The Hague agreeing to hear the case. A decision is expected later this year, despite China refusing to participate in the proceedings.
'Through legal means'
The US and ASEAN affirmed a "shared commitment to peaceful resolution of disputes, including full respect for legal and diplomatic processes, without resorting to the threat or use of force," said a joint statement.
The nations' statement did not name China, although Obama touched on the "upcoming" ruling from The Hague.
"Any disputes between claimants must be resolved peacefully through legal means such as the upcoming arbitration ruling under the UN Convention of the Law of the Seas, which the parties are obligated to respect and abide by," Obama said.
Beijing's island-building in the South China Sea
Satellite images show the extent and speed of China's land reclamation activities in disputed waters of the South China Sea. The new land masses are believed to be primarily military installations.

China is expanding the construction of its facilities on Fiery Cross Reef. Provided by the Asia Maritime Transparency Initiative (AMTI), this June 28, 2015 photo reveals Beijing has nearly completed a 3,000 meter (9,800-foot) airstrip, long enough to accommodate most Chinese military aircraft. Two helipads, up to 10 satellite communications antennas, and one possible radar tower are also visible.

Expansion
Reclamation on Fiery Cross Reef, which lies on the west side of the Spratly Islands, began in August of 2014 and its principal landmass was finished by November. Dredgers have created a land mass that spans the entire existing reef and is approximately 3,000 meters long and 200-300 meters wide.

Facilities
This picture taken last November shows construction work being carried out on Fiery Cross Reef. The reef reportedly already houses a helicopter landing pad, a 300-meter-long wharf, a harbor large enough to dock military tankers, barracks and artillery emplacements.

South Johnson Reef
This reef was one of the first facilities to finish principal land reclamation. This recent picture shows that a radar tower is nearing completion at the north end of the land mass. According to AMTI, a new large multi-level military facility has been built in the center of the island. Up to six surveillance towers are being constructed alongside four possible weapons towers.

A naval base?
Beginning in early 2015, Mischief Reef - also located in the Spratlys - has undergone extensive reclamation activity. Experts say that the recent widening of the southern entrance to the reef, coupled with sightings of Chinese navy vessels, may suggest a future role for the reclaimed reef as a naval base. Taken on March 17, this image shows a chain of small land formations at the reef.

From reef to island
Significant construction on Gaven Reef began in 2014, with a total of 114,000 square meters of land already created. Satellite pictures show just how fast construction has progressed on the reef. A new artificial island was created between March (left) and August (right) 2014.
According to AMTI, China has had a troop garrison on Gaven Reef since 2003, which has included a large supply platform where ships can dock. Experts say a new main square building in the reef appears to be an anti-aircraft tower.

A standardized process
As seen in this image, the basic process of expanding these features involves dredging sand from the seafloor and dumping it onto the reefs. The structure is raised above the high water line, hiding the status of the bank or reef beneath. The sand is then smoothed out and workers surround the island with a concrete barrier to protect against erosion and storm surge, and begin construction.

'Historic rights'
China claims most of the potentially energy-rich waterway, through which $5 trillion in ship-borne trade passes every year. The US Pacific Fleet commander recently said China was "creating a great wall of sand" in the South China Sea, causing serious concerns about its territorial intentions. Beijing argues it is asserting its so-called "historic rights" to maritime resources in the area.

Territorial disputes
The Philippines, Vietnam, Malaysia, Brunei and Taiwan also have overlapping claims, which have led to territorial disputes in the area. Last summer, China's deployment of a massive oil rig in waters also claimed by Hanoi escalated tensions in the region, sparking a standoff at sea and violent anti-Chinese demonstrations in Vietnam.

US concerns
Washington is concerned China's efforts carry a military dimension that could undermine the US' naval and economic power in the Pacific, and has weighed sending warships and surveillance aircraft within 12 nautical miles of the new artificial islands. Washington has repeatedly called on Beijing and others to end reclamation projects in the disputed waters, but Beijing rejects those demands.

Ecological impact
The Philippines filed a formal plea at the UN last year, challenging Beijing's territorial claims. Manila said China's reclamation activities are causing "irreversible and widespread damage to the biodiversity and ecological balance of the South China Sea." It also claimed that the destruction of coral reef systems is estimated to cause economic losses valued at $100 million annually.
