Instagram has been blocked in mainland China since Sept. 28, in an evident attempt to stop images of pro-democracy protests in Hong Kong as street clashes entered their third day. Following repression of the massive Occupy Central demonstration, thousands of people have remained on the streets of Hong Kong, defying tear gas and ignoring orders to disperse. Overnight, riot police advanced on crowds who ignored official warnings that the demonstrations were illegal. In what can be read as a veiled threat, Hong Kong's chief executive CY Leung reassured the public that rumors the Chinese army might intervene are untrue. (Shanghaiist, Sept. 29; BBC News, Sept. 28)

Nicaragua's Commission for the Development of the Grand Canal on July 7 approved a route for the proposed inter-oceanic canal through the Central American country. The waterway, to be built by Chinese company HKND, is slated to run from the Río Punta Gorda (South Atlantic Autonomous Region) on the Caribbean Coast to Brito (Rivas department) on the Pacific coast—a route more than three times as long as the 48-mile Panama Canal. The Commission said the canal will be operational by 2020, but questions have been raised on how the Hong Kong-based company plans to finance the project, estimated at $50 billion—nearly four times greater than Nicaragua's national economy. The canal is to be privately owned and operated. Ecologists have raised concerns about impacts on Lake Nicaragua (also known as Cocibolca), Central America's largest lake and an important fresh-water source for the country. There are fears the the water used by the canal's locks could seriously deplete the lake. The Río San Juan, which feeds the lake and forms the border with Costa Rica, would be dammed to feed the locks. Costa Rica has formally demanded the right to review environmental impact studies for the project before work begins. The Rama-Kriol indigenous people, whose territories in the Punta Gorda river basin would be impacted, are demanding to be consulted on the project. (La Prensa, Nicaragua, July 17; Tico Times, Costa Rica; July 15; Nicaragua Dispatch, Reuters, El Financiero, Mexico, July 8)

Chinese authorities carried out aggressive detentions ahead of the 25th anniversary  of the Tiananmen Sqauare massacre, with New Tang Dynasty news agency reporting 70 journalists, dissidents and rights defenders arrested over the past month. Blogger and journalist Gao Yu went missing at the end of April, and Beijing activist Hu Jia has been under house arrest for more than three months, after announcing his intention to hold a vigil in the square on the June 4 anniversary, in defiance of authorities. The Wall Street Journal's China Real Time blog notes that tens of thousands attended a vigil in Hong Kong, but the New York Times' Sinosphere blog reports that Tiananmen Square itself was so thick with security patrols and checkpoints that even the usual throng of tourists was down to a mere trickle. A tantalyzing report in the Globe & Mail says that a small group of black-clad citizens did manage to walk through the square in a silent, symbolic protest.

Pentagon chief Chuck Hagel toured Asia earlier this month ahead of Obama's coming visit, and at an April 10 stop in Ulan Bator signed a "joint vision" statement with his Mongolian counterpart Dashdemberel Bat-Erdene, calling for expanding military cooperation through joint training and assistance. "A strong US-Mongolia defense relationship is important as part of the American rebalance to the Asia-Pacific region," Hagel told a joint press conference. Bat-Erdene ruled out the possibility of hosting US forces, citing a Mongolian law that bars foreign military bases from the country. But the agreement is clearly aimed at extending US military encirclement of China. Days earlier, Hagel had lectured his hosts in Beijing over China's establishment of an air defense zone in the East China Sea. He also made a flat warning about the disputed Senkaku/Diaoyu islands, telling reporters: "We affirmed that since [the Senkaku Islands] are under Japan's administrative control, they fall under Article 5 of our Mutual Security Treaty." (AFP, April 10; Time, April 8)

Workers at six out of ten factories in Dongguan owned by Taiwanese multinational Yue Yuen Industrial Holdings have been on strike since April 14 after discovering the company has not been paying its 70,000 employees legally required levels of social security and housing contributions. At least 10,000 Yue Yuen workers took to the streets the day the strike began. Yue Yuen produces shoes for sportswear brands including Nike, Adidas and Asics. The strike is emblematic of a new wave of labor struggles in Guangdong, where Dongguan is located, and other industrial regions of China. Samsung, Lenovo, Nokia and Wal-Mart are among the companies hit by stoppages in recent weeks. Strikes are up by almost one-third in the first quarter of 2014 compared to the same period last year, according to research by Hong Kong-based China Labour Bulletin. The group's findings also reveal "a more forceful response from the local authorities," with a four-fold increase in police interventions and a sharp rise in arrests. This trend is confirmed by recent trials of worker activists and strike organizers. (Bloomberg, April 19; China Worker, April 17; China Labour Bulletin, April 14)

The current expansion of the Panama Canal will allow close to 90% of the world's 370-vessel liquified natural gas (LNG) fleet to pass through by 2015, the Panama Canal Authority announced Oct. 30. Currently the canal can accommodate only 8.6% of the global LNG fleet. Voyages to Asia from the US will cost 24% less than longer routes, according to the authority. The US, now the world's top natural gas producer due to extraction from shale rock, is projected to  become the third-largest LNG exporter by 2020. Excavation to double the Panama Canal's capacity, which began in 2007, is said to be 64% complete.

Nicaraguan civil society groups have challenged plans by a Hong Kong company to build an interoceanic canal through the Central American country. Last month, representatives of indigenous and Creole community groups from Nicaragua's South Atlantic Autonomous Region (RAAS, see map) called on the country's Supreme Court to repeal the law allowing the construction of the canal. "The passing means that the state accepts and approves in advance [a project] that will affect peoples of indigenous and of African descent, who had been excluded from the decision-making process," the Nicaragua Center for Human Rights (CINDH) said in a statement. "There has to be a consultation with the indigenous population, because this project will affect the entire population with its own traditions and way of life," said Allen Clair Duncan, head of the communal government of Monkey Point, where a deep-water port is set to be built as part of the canal project.

Nicaragua's President Daniel Ortega and Chinese business magnate Wang Jing on June 14 formally sealed a pact granting Wang exclusive rights to build a multi-billion-dollar inter-oceanic canal through the Central American nation—the night after the country's National Assembly, dominated by Ortega's Sandinista Front, voted up Law 840, a bill approving the project, by 61-25. Wang's HK Nicaragua Canal Development Investment Co. will start with a study to determine whether the project is viable. Under the plan, the company would have a 50-year contract to develop and run the canal, with Nicaragua receiving a minority share of any profits. Ortega pledges the project will eradicate poverty in the country, one of the hemisphere's poorest. "This is a historic day for Nicaragua... a day of fulfilling prophecies and realizing dreams," said first lady Rosario Murillo, during the nationally televised ceremony. Murillo called it a "day of miracles" and said the canal project represents a "prophecy of prosperity for Nicaraguan families."
