Last week Chinese military aircraft interceprted US reconnaissance planes near the island of Hainan and the upcoming conference on mechanisms of maritime military security on June 24-25 is thought to prove the "capabilities of military channel as well as good relations between Washington and Beijing."
He added that the concerns are caused by attempts by Moscow and Beijing to expand their influence in Eastern Europe and the Pacific region.
Chinese military expert Zhang Junshu said in an interview with Global Times newspaper that the increased number of US spy planes near Chinese and Russian borders is a serious violation of their state security.
Gen. Carlisle also said that the number of Russian long-range bombers in Eastern Europe and near the US west coast is increasing while China wants to take control over the South China Sea.
"Our concern is a resurgent Russia and a very, very aggressive China," he said.
"Their intent is to get us not to be there… So that the influence in those international spaces is controlled only by them. My belief is that we cannot allow that to happen. We have to continue to operate legally in international airspace and international waterways," he added.
The majority of interceptions of US spy planes took place near the borders of Russia and China, the analyst said.
The US admitted that last year the Pentagon conducted over 700 patrols in the South China Sea, including over 100 spy flights.
He also said that despite the fact that Beijing and Washington have agreed a number of maritime security memorandums China will not turn a blind eye to the US’ surveillance activities.
Over the last three weeks, RC-135 spy planes of the US Air Force have approached Russian borders 14 times, including over the Baltic Sea, in the Murmansk Region and in the Far East.
The latest incident took place on Sunday when an RC-135V plane flew near the Russian border over the Baltic Sea. The aircraft, tail number 64-14844 and call sign TROG34, took off from the Mildenhall airbase in Britain and flew in the southern part of the Baltic Sea.
"In the 1990s, the US didn’t conduct reconnaissance flights over Russia because at the time the Russian military was weak. Now, they are concerned with the resurgence of Russia’s military power. This is why the Pentagon has intensified aerial intelligence," expert Vladislav Shurygin was quoted as saying by TV channel Zvezda.
