China and the United States are gearing to unveil plans aimed at averting the possibility of military conflict between the two powers as President's Xi Jinping and Barack Obama meet on Wednesday, according to U.S. officials cited by the Wall Street Journal on Tuesday.

One such plan involves the creation of a communication channel meant to act as an early warning notification of major activities each side plans to carry out, particularly those of military exercises.

A framework outlining acceptable rules of conduct in case of air and sea encounters is also included, officials with knowledge of the negotiations said.

A second agreement dealing with climate change is also in the works, the WSJ report detailed.

U.S.-China relations have deteriorated in the past year following accusations of cyber espionage from both sides and over Beijing's aggressive approach in asserting sovereignty in disputed territories also claimed by others including the Philippines and Japan, both Western allies.

Additionally, human rights violation allegations with regard to protests in Hong Kong did not help matters.

On Monday, Obama spoke in support of pro-democracy activists and called on China to respect the basic freedoms of right to expression, speech and to an open government, the Los Angeles Times relayed.

White House aides have declined to give additional details on the agreements but National Security deputy adviser Ben Rhodes said both sides have expressed willingness to establish protocols to avoid accidental encounters that could escalate into conflict, referring to previous instances when U.S. and Chinese militaries had come "too close for comfort."

China's Ministry of Defense likewise declined to elaborate on the agreements but allowed that an early military warning system and a guideline for rules of conduct would have a positive impact on bilateral trust and military cooperation.

Cyber spying issues are also on the agenda for Wednesday's Xi-Obama talks.
